You know you're having a rough night when Miley Cyrus steps in. Jennifer Lawrence, who was nominated for her role in "American Hustle," told Seth Meyers all about her wild night after the show was over.

According to an audience member who watched the taping of Lawrence's appearance on "Late Night," the actress was "wasted" at the March 2nd show, so much so she ended up throwing up on the stairs of Madonna's post show bash. Best, most Hollywood twist? Miley Cyrus witnessed the whole thing.
