We can think of so many reasons why!

Blac Chyna ran errands around Sherman Oaks in her new Ferrari yesterday, and while she's normally more than happy to have her picture taken, this time she did her best to hide behind her phone. Maybe she's trying to keep herself from talking smack about Rob Kardashian? Or perhaps she just got fresh lip injections? Either that, or all her recent hookups are catching up to her and she has a nasty cold sore.

We asked the former stripper about Rob's alleged recent weight gain, but she opted to keep her trap shut. That's probably best, considering they're still hammering out a custody arrangement over daughter Dream, and anything she does or says can be used against her.

"Rob and Chyna's lawyers are working out the details of their custody situation quietly. Chyna and Rob don't talk to each other at all. Only the lawyers are in communication with each other. They're doing this so they can get along for the sake of Dream. The case will be done and closed quietly," a source dished to Radar.

Let's hope grandma Kris Jenner and some nannies are helping out, because it sounds like the reclusive sock designer isn't in very good shape physically or mentally amid all this drama.

"He's the biggest he's ever been. He's well over 300lbs now – we don't know as the scales don't go up past that – and he's a heart attack waiting to happen. He's been comfort eating big time. His fridge has become his best friend," another source divulged to the site.

"Kris has cut him off as of now and she won't be handing him another dime until he confronts his problems. He's got major anger and addiction issues, brought on by a chronic lack of self-esteem over his looks and his position in the family. He's lost the will to live and if it wasn't for his little girl he'd probably not have made it," the source added.

We wonder what her next move will be? You just know she's scheming!

Not like that's anything new, though!

Kourtney Kardashian ran errands with son Mason yesterday, and we've got to hand it to the reality star for basically being a single parent. Although Scott Disick is still in the kids' lives, he's been prioritizing partying and womanizing in recent weeks. In fact, just this past weekend, he was spotted wasted and begging for oral sex at a Hamptons bar.

The mother-of-three and her baby daddy have struck an agreement about co-parenting, but she's not very hopeful that he will abide by it.

"She wants nothing more than to have him live by his word, but she still has it at the back of her mind that he will disappoint her. Kourt needs to have him in her life because of the kids since they always ask for him, but she still thinks he will mess up again. She hopes not, but he has disappointed her before so she expects it again," a source dished to Hollywood Life.

The eldest K sister has totally shut the door on a reconciliation, though.

"Kourtney always ends up forgiving Scott, no matter how badly he has behaved, he’s her kryptonite. That said, Kourtney has finally gotten to the point where she no longer wants to be in a relationship with Scott, she’s finally managed to realize it’s never going to work," the source added.

We wonder how long it will be before she introduces boy toy Younes Bendjima to her brood?

She likes it all!

Kristen Stewart has had serious relationships with both men and women, and her sexual experimentation was a deliberate choice she made, she told Harper's Bazaar in a new interview.

The Twilight star used an interesting analogy when describing her gender fluidity.

"Some people know they like grilled cheese and they'll eat it every day for the rest of their lives. I want to try everything. If I have a grilled cheese once I'm like, 'That was cool, what's next?'" she explained, in reference to her sexual preference.

Just because her sex life is all over the map doesn't mean she didn't truly care about each one of her partners.

"I've been deeply in love with everyone I've dated. Did you think I was faking it? I've always embraced a duality. And really, truly, believed in it and never felt confused or struggling. I just didn't like getting made fun of," she confessed.

Her most high profile romance was with Robert Pattinson, and she's now happily dating Victoria's Secret model Stella Maxwell. We think we'd swing both ways, too, if they were our options!

Sounds like they're hitting their stride!

Jennifer Aniston and Justin Theroux had "difficulty" early on in their marriage, but they've now reached a good place and are happier than ever two years in, People reports.

"It took them a while to figure everything out. [Getting married] was a big deal for both of them," a source dished to the mag.

Being older and wiser helped them to avoid pulling the plug when things got rough.

"[Jen and Justin] still very much act like newlyweds. They love to laugh and share a wicked sense of humor. It’s possible that this marriage would not have worked as well if they were in their 20s, but they aren’t. They are great friends and have total respect for each other," the source explained.

While their hectic schedules and careers keep them apart a good portion of the time, they've learned to adjust their expectations and treasure the time they do get to spend together.

"Jen realized that you can be happily married without being together 24/7. They have so much to catch up on and it makes their marriage more exciting. Justin can still make Jen blush. She still talks about how she finds him very sexy. Not seeing each other every day makes them appreciate each other more," the source added.

We think they make a great match. Happy anniversary lovebirds!

Good thing she's already perfect!

Sofia Vergara stripped down for the newest issue of Women's Health and talked all about how her famous assets have inhibited her athletic abilities, but it's pretty clear she doesn't need to waste any time in the gym!

"I don’t know if I’m strong. I have bad knees and very thin bones; I can barely do a pushup. I wish I could be a little more athletic, but when you’re born with these gigantic boobs… I’ve had them since I was 13, and then they got bigger when I was pregnant and had the baby. It’s not about having muscle or cut abs. I don’t have abs because I’m not 'I need to be like a fit model with a perfect body.' That would take too much effort!" she confessed to the mag.

She's considered one of the sexiest women on the planet, but even she struggles with getting older.

'I’m 45. Even if you want to, at this time in your life, you can’t be perfect. It’s not that you hate it, or that you’re upset about it, but it is our reality. We’re changing. I see it happening to me. I want to look my age, but I want to look great. I think if you are obsessed with this 'I want to look younger' thing, you’re going to go crazy," she explained.

"People say, 'Oh, you look like you’re in your twenties.' Well, it’s not true. Our skin is different. I had never thought of the word pore, then I’m like, 'S**t! What do I do with these?'" she added.

We just don't feel sorry for her!

They're inseparable!

Ben Affleck and Lindsay Shookus are back on the West Coast after their whirlwind trip to NYC and Maine, and the first thing they decided to do was hit up a comedy show at iO West in Hollywood followed by a romantic oyster dinner at Osteria Mozza. The SNL producer was carrying head shots and bios, and we have a feeling the actor tagged along while his lady love scouted new potential talent for her late night program.

An insider tells X17:

"Ben is happier than ever. Lindsay is just a normal girl with a somewhat normal job. He's relieved he's not part of a "power couple" anymore. He had instant chemistry with Lindsay, and their love has only grown. He feels like he can be himself with her, and he never really felt that way with Jen. He was always trying to be who she wanted him to be, and with Lindsay, she just makes him feel like the world's most perfect guy."

Considering these two began an affair three years ago and torpedoed their respective marriages in the process, we have a feeling this relationship will go the distance. Rumors are even swirling that they're considering having a kid together!

"They’re actively talking about having a baby. They’re ready to start a family," a source recently dished to In Touch.

This whole situation is every ex-wife's worst nightmare! Speaking of, earlier in the day, Jen and Ben's mom Christine Anne Boldt were spotted taking an affectionate stroll in Brentwood. It doesn't look like the Oscar winner's mother is happy her son is moving on!

Yeezy wants his money, and they don't want to give it to him!

Kanye West filed a federal lawsuit Tuesday against insurance company Lloyd’s of London, and alleged they are dragging their feet and looking for excuses not to pay out the money lost when he had to cancel the rest of his Saint Pablo tour following his mental breakdown in November. He wants $9.8 million plus interest.

Very Good Touring, the company handling the tour, claims it filed the claim back in November, but Lloyd's of London has been unresponsive. "The stalling is emblematic of a broader modus operandi of the insurers of never-ending postclaim underwriting, where the insurers hunt for some contrived excuse not to pay,” their lawyers alleged in court documents.

Lloyd's is suggesting that Yeezus' marijuana use could have contributed to his mental health hospitalization, and that they might not have to pay out a dime.

According to In Touch, Kim Kardashian testified under oath about her husband's breakdown back in December, and was asked about the music icon's drug use.

We knew they would think he was faking this whole thing!

A post shared by Miley Cyrus (@mileycyrus) on Jul 31, 2017 at 5:52pm PDT

This is her in her most natural state!

Miley Cyrus shared this topless photo of herself in bed with her dogs on Instagram yesterday, and it's like getting a glimpse into her everyday private routine. Her pooches are the cutest! The only thing that could have made this snapshot more adorable would have been her fiancé Liam Hemsworth.

The couple are doing OK now, but they almost called it quits over a prenup last month, OK! Australia reports. "They got into an explosive fight. Miley told her friends that Liam got furious. They never yell, but they were screaming and in tears. [Miley] thought he was going to end the relationship," a source dished to the mag.

The "Wrecking Ball" singer has been going through a lot of transformations in recent months, and recently explained to Harper's Bazaar why she decided to ditch her wacky, raunchy image.

“I feel really kind of far away from that person. I just want people to see that this is who I am right now. I’m not saying I’ve never been myself. … Who I was on the last record was really who I am. It’s just myself has been a lot of different people because I change a lot," she told the mag.

"It became something that was expected of me. I didn’t want to show up to photo shoots and be the girl who would get my tits out and stick out my tongue. In the beginning, it was kind of like saying, ‘F--k you. Girls should be able to have this freedom or whatever.’ But it got to a point where I did feel sexualized," she added.

Ultimately, she's happier than ever as she goes through this metamorphasis.

"I think I’m just figuring out who I am at such a rapid pace that it’s hard for me to keep up with myself. People get told that it’s a bad thing to change. Like, people will say, ‘You’ve changed.’ And that’s supposed to be derogatory. But you are supposed to change all the time," she confessed.

She's really coming into her own!
