Bella Hadid went to lunch at the Beverly Hills Hotel on Monday for her dad's birthday, and she posted a handful of silly Snapchats from the celebration. But what caught our eye was her figure -- and the fact that's she looking a little waify these days!

The 20-year-old model, who is preparing to walk in her very first Victoria’s Secret Fashion Show next month, admits she shed some pounds recently. “I have lost weight and gained weight,” she told People. “My weight fluctuates so much. I really didn’t mean to [lose weight]. Like I want boobs. I want my ass back. But it’s not my fault. My weight fluctuates and so does everybody’s and I think that if people are gonna judge, that’s the worst you can possibly do because everybody is different.”

So what happened? Bells says she “accidentally” slimmed down by sticking to a strict diet and intense workout plan. “I worked out so hard and everybody is like, ‘Oh, she looks so skinny blah, blah, blah,'” she revealed. “But I think that if you just stick to something you can really achieve so much. I’ve been eating hard protein every day, and working out for three hours every day. It’s crazy but I think that you know if you set your mind to something I think you can succeed.”

“I think every single person in the world has insecurities,” she continued. “It’s crazy because I think that when other people look at all of the VS models or all of the girls [who] are walking, they’re like, ‘They’re not human. They don’t have any insecurities.’ But I think every single girl [who’s] going to be walking probably has an insecurity.”

Hers? “I wish my ass was bigger,” she admits. Maybe big sis Gigi can take her out for a burger in NYC...we hear she's quite the fan!

WTF?! Could Kourtney Kardashian really be pregnant with her FOURTH child?! And uh ... who would the daddy be? Is KK still hooking up with baby daddy Scott Disick, even though they've separated? I mean, Bieber's been gone for a hot minute, so we're guessing he's not the father :)

Kourtney was at the family gyno on Monday, playing with her T-shirt and drawing some attention to her mid-section. And you know us, we're all too happy to jump on the is-the-skinny-celebrity-pregnant train!

Brad Pitt and Angelina Jolie have reached a custody agreement for their six kids -- and it's the same as the temporary agreement that was worked out a few weeks ago. Maddox, 15, Pax, 12, Zahara, 11, Shiloh, 10, Knox and Vivienne, 8, will remain in Angelina's custody while Brad will have supervised visitation with a therapist.

A representative for Jolie said in a statement:

"We can confirm that childcare professionals have encouraged a legal agreement accepted and signed by both sides over a week ago. In accordance with this agreement, the six children will stay in their mother's custody, and the children will continue therapeutic visits with their father. This has been determined by childcare professionals to be in the children's best interest. We are not in a position to discuss the details. We hope now that it is clear that the events which led to the dissolution filing involved minor children and their well being, there will be understanding of the sensitivity of the family situation. We believe that all sides are committed to healing the family and ask for your consideration during this difficult time."

Last Friday, Brad filed for joint custody, and while he has agreed to the above conditions for now, he hasn't withdrawn his petition, which protects his rights in the future. So why settle? No one really knows, but it might have to do with media coverage. “Unlike Jolie’s side, Brad’s side is actually attempting to abide by the confidentiality agreement that both parties signed, something Angelina’s side has no interest in doing,” a source close to the Jolie-Pitt child custody battle told Entertainment Tonight. “From the beginning, Brad only wants to do what’s best for the children, and that’s not fighting this in the public press.”

“This is what Brad and Angelina have decided between each other for the children,” a source added to ET. “The agreement is also indefinite, so there is no time frame to it, it is in place until they decide to make a change. This is a good sign, it is the first step. This means one issue is now off the table for them.”

But is it though? If Brad hasn't withdrawn his petition and this is "indefinite," that doesn't sound very permanent to us!

She's gorgeous, that's all there is to it!

Renee Zellweger has been the victim of nasty plastic surgery rumors for years, but we think these pix of her yesterday out in the Hollywood Hills should put those to rest once and for all! The actress was smiling and positively glowing as she strolled with a pal, and she looks exactly like she did back in her Jerry Maguire days.

"Not that it’s anyone’s business, but I did not make a decision to alter my face and have surgery on my eyes. This fact is of no true import to anyone at all. Although we have evolved to acknowledge the importance of female participation in determining the success of society, and take for granted that women are standard bearers in all realms of high profile position and influence, the double standard used to diminish our contributions remains, and is perpetuated by the negative conversation which enters our consciousness every day as snark entertainment," she wrote in an op-ed for Huffington Post.

"Maybe we could talk more about why we seem to collectively share an appetite for witnessing people diminished and humiliated with attacks on appearance and character and how it impacts younger generations and struggles for equality," she added.

We admit her appearance is none of our business, but we wanted her to know we here at X17 think she's beautiful!

Soon 😎

She's dying to regain her pre-baby bod!

Blac Chyna's goal was to gain 100 pounds during her pregnancy - and she almost succeeded! - but now the video vixen is looking forward to shedding the baby weight a la Kim K! "Soon," she captioned a throwback photo of herself in skinnier days.

ChyRo is set to welcome their baby girl next week via C-section, and the model will give birth in the same birthing suite as her future sister-in-law. The $4000-a-night room at Cedars-Sinai Medical center has three beds, two baths, and a lounge area. That's a lot of space for the big event, but they need it! The controversial couple has agreed to allow reality cameras document the whole thing for the new season of Rob & Chyna.

Let's hope Chy realizes how hard it is to "snap back." Kim had a bazillion dollars to spend on private trainers, chefs, and plastic surgeons after giving birth to son Saint, so it's really not as easy as it looks!

After spending the weekend with Kris Jenner for her birthday, Khloe Kardashian jetted off to Cleveland, Ohio on Sunday to see her main man, Tristan Thompson, who plays for the Cavaliers. Looks like Khloe's been bitten with the love bug!

The blonde certainly turned heads at LAX when she donned a skintight bodysuit, bomber jacket, knee-high boots and plaid shirt, wrapped around her skinny waist. She looks amazing!

It's clear things are going well for Khloe and Tristan since the reality star, who was definitely still sporting that diamond sparkler on her ring finger, was geared up to go see her man after a weekend with the fam. The 32-year-old has been flying at least once a week (sometimes more) to see her NBA star boyfriend. She's really racking up those frequent flier miles!

On Saturday, Khloe and her sisters attended their mom's birthday party. The family rented out the Westlake Village Cinepolis (as they had previously, for Kim's birthday) for a private showing, and then migrated over the The Grill for a casual dinner.

Is she refusing to let go, or is she just trying to rub it in that she got to keep the bauble?

Mariah Carey and DJ Khaled grabbed dinner at celeb hotspot Catch over the weekend, and the legendary diva was noticeably still donning her massive engagement ring from ex-fiance James Packer. We know that they're in the middle of tense negotiations over a reported $50 million split settlement, so she must be trying to send the Aussie billionaire some sort of message.

Mimi also brought along backup dancer and rumored boy toy Bryan Tanaka for the outing, and if she's trying to make her former beau mad, we're sure it's working.

She hasn't exactly been sitting at home and crying since her relationship fell apart. The Grammy winner and backup dancer Tanaka took her kids trick-or-treating around her Calabasas neighborhood on Halloween, and were spotted enjoying a pizza date at Berri's Cafe in West Hollywood later in the week.

While the hit-making bombshell is running around town trying to make Packer insanely jealous, her other ex Nick Cannon is on daddy duty. We caught the TV star leaving a toy store with twins Moroccan and Monroe on Sunday, and we're dying to know what he thinks of all this!

This uncoupling is anything but a sweet sweet fantasy!

Good thing they were parked!

Ben Affleck and Jennifer Garner went for a drive around Brentwood this morning with their son Samuel, and the A-list actor let the little one hop into the driver's seat while they were at a standstill for an impromptu lesson behind the wheel. Don't worry, though, he didn't pull a Britney Spears and hit the road with his kid on his lap!

Yesterday, the Batman star took his brood to church, and he has really been stepping up to the parenting plate lately despite his insanely busy work schedule. We have a feeling this is part of his plot to win back Jen G for good. The pair spend nearly every day together, and there has been no motion to speak of on their divorce.

The former couple have chalked up their chummy relationship to amicable co-parenting their three children, but they've been spotted on numerous occasions going to dinner just the two of them, and the Boston hunk even moved back into the Pacific Palisades family home back in September. All signs point to a reconciliation!
