J. Law's ready to party! Jennifer Lawrence turned up the sex appeal at the Vanity Fair Oscars bash on Sunday, March 2, trading her sleek red carpet Dior Haute Couture gown for an edgy Tom Ford mini that required her to go without underwear at the annual Graydon Carter-hosted event.

The frock featured a metallic shattered-glass design and sheer paneling on the sides and back that left slivers of the Oscar nominee's bare hip and thigh exposed. She also made over her makeup, upgrading her cat-eye to a sexy smoky eye.

The 23-year-old American Hustle star had quite the night, despite losing the Best Supporting Actress Academy Award to 12 Years a Slave newcomer Lupita Nyong'o. Upon arriving at L.A.'s Dolby Theatre before the show, she tripped over a cone and fell into a woman in front of her — which made her a prime target for host Ellen DeGeneres.

"Jennifer Lawrence, by the way, I'm not going to bring up what happened last year," DeGeneres quipped in her opening monologue. "It's ridiculous. Something like that happens and it's embarrassing, and then people just talk about it. For those of you who don't know what I'm talking about, last year she fell on her way up. Let's just show the clip," the host joked.

"And you know the thing about when you fell out of the car tonight when you were getting out the car? No one needs to know about that," DeGeneres continued. "I'm not going to mention that. She fell on the way out of the car," the Oscar host explained to the crowd. "Like, on an orange cone, you tripped or something. If you win tonight, I think we should bring you the Oscar."

The hijinks continued even after Lawrence's Oscar loss. Backstage, she jokingly tried to steal "rival" Nyong'o's trophy away.
