Jennifer Lawrence is showing off her sexy side!

The "American Hustle" starlet turned heads at the Vanity Fair Oscars Party on Sunday night, trading in her classic red Dior Haute Couture gown for an edgy Tom Ford mini.

Her sexy dress 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 clearly wasn't wearing any underwear at the star-studded bash! 

The blonde beauty may not have taken home Oscar gold, but she certainly seemed to enjoy the Academy Awards.

She was part of the most epic selfie of all time, posing for a candid snapshot during the show with host Ellen DeGeneres, Bradley Cooper, Brad Pitt, Angelina Jolie, Kevin Spacey, Julia Roberts, Meryl Streep, Lupita Nyong'o, Jared Leto and Channing Tatum.

The pranks continued after J. Law lost the Best Supporting Actress award to Lupita. She was photographed jokingly trying to steal the trophy away from the "12 Years a Slave" star.

And, of course, she also tripped the second she hit the red carpet.

We love to see Jennifer Lawrence's silly side!
