He has already lost a lot of weight, but it appears he's kicking his fitness routine into overdrive now that he's set to walk down the aisle!

Rob Kardashian hit the gym in L.A. in this morning to work out with his trainer, and we have a feeling he's more motivated than ever to shed those last extra pounds before his wedding to new fiancee Blac Chyna. Kimmy K's little brother popped the question to his girlfriend last night with a $325K sparkler, and all signs point to a relatively short engagement given how fast these two have been moving in the romance department!

Tyga's baby mama has really brought the reclusive sock designer back from the brink, as he battled depression and eating issues for years before they got together. Rob's famous family reportedly recognized the makeup mogul's positive influence on him, so they were slowly coming around to the idea of them being a couple before news broke they plan on tying the knot. Tellingly, none of the K clan have taken to their social media accounts to send their well-wishes yet, so this latest development might not have gone over so well.

Rob seemed stressed as he drove away after his sweat sesh, and we wouldn't be surprised if Kris Jenner has been calling nonstop trying to talk some sense into her only son! After all, once he and Blac Chyna wed, she will legally be a Kardashian and allowed to use the name however she pleases!

Poor little pretty girl!

Charlize Theron covers the latest issue of British GQ, and she talks all about how being beautiful is actually a disadvantage in Hollywood. The South African stunner's good looks landed her a major Dior campaign, but they've made it a lot harder to snag quality roles in films.

"Jobs with real gravitas go to people that are physically right for them and that's the end of the story. How many roles are out there for the gorgeous, f**king, gown-wearing eight-foot model? When meaty roles come through, I've been in the room and pretty people get turned away first," she lamented.

The blonde bombshell gained a bunch of weight and wore a prosthetic nose for her Oscar-winning performance in Monster, and shaved her head for Mad Max, but her latest role as Evil Queen Ravenna in The Huntsman: Winter's War shines the spotlight on the pressure put on women to maintain a youthful appearance.

"We live in a society where women wilt and men age like fine wine. And, for a long time, women accepted it. We were waiting for society to change, but now we're taking leadership. It would be a lie to say there is less worry for women as they get older than there is for men … It feels there's this unrealistic standard of what a woman is supposed to look like when she's over 40," she griped.

We would deal with a little bit of hardship to look like her!

Britney Spears wants you to know those abs of steel of hers are real!

After being accused of Photoshopping her rockin' bod', the singer wished her followers a "Happy Monday" yesterday. Take that, haters!

In the pic, the pop star is wearing wearing short shorts and a peasant-style top with caped sleeves. Of course, the snap accentuates her fit form and her glowing tan post her trip to Hawaii with her two sons.

Looking good, lady!

It appears as if BritBrit is posting a plethora of photos showing off her toned body after she share a photo with her 9.4 million followers and was accused of slimming her stomach. Looks like the haters were wrong!

She probably never thought she'd see the day!

Caitlyn Jenner won the coveted Outstanding Reality Program prize at the GLAAD awards in LA on Monday night, and the transgender TV star couldn't help but get emotional talking about her friends and co-stars during her acceptance speech.

"I had never met anyone who was trans and we sat down and we had dinner. We had the most wonderful time and that relationship started then, and its only grown and grown and grown. You girls have been the backbone, you've taught me so much, I've learned so much from you from you this last year. You're my absolute best friends and I know you'll always have my back and its been just wonderful to work with you. I know when we finished season two I was literally crying because I couldn't stand going through life without you girls around," she said while choking back tears.

The Olympian also shared her pride in being able to expand awareness on trans issues.

"It’s been such a wonderful experience being able to shoot this show. We’re trying to make a difference. We’re trying to make the next generation of trans people out there, make it seem more normal. I had never met another trans person. I lived my life in silence, I suffered on my own. As so many people in this room have such a difficult time coming out and being your true self and being who you are, it is a long struggle... but the last year has been the most rewarding year of my life," she added.

Life is sweet for Cait these days!

Iggy Azalea is done.

After last week's cheating scandal with fiancé Nick Young, Iggy is having none of this "IRS" hoopla.

On Monday, Iggy hit back after reports surfaced that she was having issues with the IRS and had a tax lien placed against her for almost $400,000 of unpaid income taxes from 2014. But the singer shot down the rumors via Twitter that the lien document was taken out of context and she's not trying to cheat her way out of paying her taxes.

The Aussie wrote, "The IRS gave the option to pay them monthly or lump sum. i picked monthly, who wouldnt?"

The "Fancy" lady also added that she'd made the deal two months previously.

The rapper was also quick to add that the only reason that people are reporting this story is because of all her drama with her fiancé.

We kind of agree -- we passed on the original story 'cause we thought it was kind of a snoozefest. We are glad that Iggy is slamming this trumped up tale.

Time for his famous family to officially freak out!

Rob Kardashian reportedly popped the question to girlfriend Blac Chyna last night, and clearly he got the answer he was looking for, because almost immediately the former stripper posted a photo of her bauble and her new fiance with the caption, "YES!" Close pal Amber Rose appeared to confirm the big news with a tweet. "Congratulations to my Family @blacchyna and @robkardashian!!! 💍💍💍😍😍😍😍😍," she wrote later in the evening. The pair celebrated their relationship milestone by partying at Ace of Diamonds strip club. Classy!

They've only been dating a few months, and the whole Kardashian clan has been none too pleased about the romance from the get-go, so it remains to be seen how this turns out. Kris, Kim, Kylie, and the rest of the girls have yet to respond to the engagement on social media, and we have a feeling the well wishes aren't exactly going to be pouring in.

How awkward is this for Kylie and Tyga? Now the rapper's son's stepdad is going to be his girlfriend's brother!

Free City? Seeing as she's not wearing a bra underneath this sheer white tee, it was more like free boobies when we spotted Kaley Cuoco on Monday!

The actress stopped by a gas station in Los Angeles to fill up the tank on her black Range Rover, and when we snapped her picture, she didn't seem to want any of it. She may be wearing Givenchy sandals and Free City sweatpants that cost as much as a car payment, but this is not the best look for the uber-rich actress.

So who's she dating these days? Apparently the lucky guy is Karl Cook, son of the tech billionaire who invented TurboTax and Quicken. Cook also rides horses, and interestingly enough, Kaley's Instagram handle is @normancook, so it's almost a little too perfect. Wonder how many months this romance will last?

Meghan Trainor arrived at Los Angeles Airport to catch a flight out of town on Monday, and the pop singer was all smiles as she made her way into the terminal. We're wondering if sitting next to dreadlocked hottie Justin Bieber at the iHeartRadio Awards the previous night might have had something to do with that? We kid, we kid -- this starlet is always in a good mood, and that's why we love her!

The 22-year-old singer chatted with E! News hottie Jason Kennedy at the show, and he asked her about being sexy -- in front of her father! Meghan brought her pops as her date, and without missing a beat, she answered the question. "It's very simple," she joked when asked about her dating life. "They don't come up [to me]. They're probably scared or intimidated. That's fine. I'm waiting for the right one. He's close. I don't think he's close. I'm 22. I'm fine with it." Her dad chimed in, "She's got plenty of time to look around."

So what about sitting next to the Biebs? "My parents love Justin, they're big fans and they were very proud of how hard he works," Meghan said when X17 photogs caught up with her yesterday. So would she date the pop star? "No, I don't know," she replied. "I'm single and working hard. He's working hard." On making the perfect couple with Biebs, she added, "Nope, not with a headliner like that." Interesting!
