Katniss looks straight off the catwalk!

Jennifer Lawrence turned heads at The Hunger Games: Catching Fire Hollywood premiere last night in a sheer Dior Haute Couture gown, and we're pretty sure nobody even noticed her other co-stars walk down the red carpet!

Joined by castmastes Liam Hemsworth, Josh Hutcherson, Elizabeth Banks, and others, the Oscar winner stole the show in her see-thru dress, which perfectly complimented her new short 'do.

"She's a great actress and she's going to constantly evolve. And I think that's going to happen with the films that she does and with the way she dresses. And cutting her hair. I think it's fantastic," she stylist Trish Summerville told USA Today.

Last weekend, Hollywood's most in-demand star revealed to French magazine Madame Figaro that she suffered from social anxiety as a kid, but we think it's safe to say that's no longer a problem based on this ensemble!

Kanye West knew who he wanted as his sexy-hot hookup for his "Bound 2" music video -- non other than his fiance Kim Kardashian, of course! And no one else could've done it better!

The singer debuted his new clip on Ellen, showing off Kim perched on a motorcycle, arching her back, then facing the camera with the wind blowing in her hair and finally, making out with her hubby-to-be on a vibrating motorcycle -- NUDE! This is one step away from her porno Kim K Superstar!

Frankly, we turned down the audio and just watched ... sounds like Kanye better come up with some new beats ...

On Monday night Kim Kardashian stepped out in New York City, and Kanye West wasn't with her, but he certainly left his mark with her outfit! C'mon ... is this sheer white top and skintight skirt something Kimmy would really pick out for herself?

We're not sure who's watching baby Nori, but Kim has been tagging along with Yeezy for the last few days for his concerts on the east coast, and more notably, his guest lecture at Harvard University in Boston.

In other Kimye news, she'll be starring in his new music video for "Bound 2," according to Us Weekly. The video will premiere on The Ellen DeGeneres Show later this morning, and not much is known about the clip, but an insider tells the mag, "Kim looks beyond gorgeous. It's very artsy, very beautiful. The imagery is very colorful and light. Nothing about it feels pop or urban. She looks incredible."

Oh, and as usual, there was plenty of booty too:

He keeps getting better with age!

Ben Affleck spent his afternoon running errands in Brentwood yesterday, and the hunky actor looked like he'd put on his Sunday best in slacks, brown loafers, and a blue velvet blazer. Maybe he's not a sweatpants and trainers kind of guy?!

Earlier in the day, we caught the A-lister picking up eldest daughter Violet from basketball practice, and we have a feeling we are going to see him on daddy duty a lot more while wife Jen Garner promotes her latest film Dallas Buyers Club.

We still can't wait to see him on the big screen as Batman!

Not quite what we consider workout gear!

Anne Hathaway went on a Sunday walk with husband Adam Schulman and some pals, and the Oscar winner donned starry leggings and a denim button down that just happen to show off her much curvier physique!

The actress just celebrated her 31st birthday over the weekend with a yummy dinner at Mr. Chow's in Beverly Hills, and it was quite the star studded bash with guests like Sidney Poiter and Christopher Nolan.

The brunette beauty is currently filming Interstellar, which centers around a group of explorers who make use of a newly discovered wormhole to surpass the limitations on human space travel, so maybe her cosmic spandex choice makes sense after all!

Over the weekend Rihanna posted a few selfies of her new bob and bangs, and we have to say, we love this look for the 25-year-old R&B starlet! As long as she doesn't go back to long red curls, we'll always dig her 'dos...

In other news, RiRi will receive a major honor at the American Music Awards this Sunday, where she'll also be performing. Producer Larry Klein said in a statement, "The first-ever Icon Award was created to honor an artist whose body of work has made a profound influence over pop music on a global level. Rihanna’s iconic and innovative sound has enabled her to become one of the most influential and best-selling artists of all time."

And in case you missed it, here's the music video for "What Now," which was released on Friday:

Despite being in a vicious custody battle with ex husband Charlie Sheen, Brooke Mueller looked calm as she walked her dogs on Sunday in Los Angeles. The 36-year-old took her two pups on a dog walk and was accompanied by a friend.

Just last week, Brooke cooperated with authorities and agreed to have her four-year-old twins Bob and Max tested for fetal alcohol and drug syndrome, according to Radar.

Last week, Brooke met with the Los Angeles Department of Children and Family Services after Denise Richards, who was caring for the boys at the time, wrote a letter detailing the boys' disturbing behavior and stating that she no longer wanted custody of them.

Mueller’s brother, Scott, was granted temporary guardianship of the twins, and a source close to the situation tells the website, “The good news is that they will now be properly tested, and monitored. It will be crucial that DCFS follows up and follows through with whatever the testing reveals. The boys' lives literally depend on it.”

Multiple sources confirmed to Radar that "Brooke did indeed also drink large amounts of alcohol while pregnant ... This was on top of the drug use which included meth." Not only that but she also went to rehab twice during her pregnancy ... Yikes!

Charlie Sheen has been very vocal about Brooke being an unfit parent, as he posted numerous messages Twitter last week, slamming his ex-wife for being "evil" and "pathetic."

Hello baby bump! Reality star Kim Zolciak has no problem flaunting her pregnancy curves, posting an Instagram pic of her prominent baby bump on Sunday. And it looks like Kim is about to pop -- that's because she is! The Don't Be Tardy star is pregnant with twins and is about to give birth any day.

Along with the revealing pic, the 35-year-old wrote, "Sooooo with all the request I finally decided to post My baby bump today! The twins will [be] here this month and we are soooo excited and I'm soooo over being pregnant! #countingdownthedays"

The former Real Housewife of Atlanta star already has four children, two from previous relationships and two with her husband, NFL player Kroy Biermann.
