Jennifer Lawrence at the Oscars

Jennifer Lawrence at the Oscars

Jennifer Lawrence allegedly "puked" in front of Miley Cyrus after the Oscars.

The 'American Hustle' star, who lost out on the Best Supporting Actress award to Lupita Nyong'o at the ceremony in March, reportedly admitted that she and her best friend, Laura Simpson, got "wasted" at Madonna's star-studded annual after-party in Los Angeles during an upcoming episode of NBC's 'Late Night With Seth Meyers' that will air on May 21.

An audience member told Us Weekly magazine: "Jen said she was so drunk, she puked on the stairs at Madonna's after-party, and Miley walked by and said something like, 'Get it together, girl!' "

The 23-year-old 'Hunger Games: Catching Fire' star - who has just been crowned the 'Sexiest Woman in the World' by FHM magazine - also spoke about hanging out with Brad Pitt at the party.

The source said: "Jen said he smelled like sandalwood. She was so fun!"

Jennifer clearly likes to let her hair down during award shows, as it was previously reported that the blonde beauty, who is dating British actor Nicholas Hoult, got "trashed" at the pre-Globes Sony party held at the Beverly Hills Hotel in January.

She was also visibly shaking as she accepted an award at the Golden Globes the following night, and told reporters backstage: "I need to catch up on my drinking. I think that's why I was so manic. I normally have time to have a glass of wine."
