Jennifer Lawrence: I once took drug while filming 'The Hunger Games'

Oscar-winning actress Jennifer Lawrence once took a drug during the production on 'The Hunger Games,' but that was unintentional. The Oscar-winning actress, 25, made the shocking revelation when playing a game of 'True Confessions' with Jimmy Fallon and John Oliver on '

The Tonight Show Starring Jimmy Fallon

,' reported Ace Showbiz.

"I once took an Ambien before filming a scene in '

The Hunger Games

'," she said, letting the two funnymen guess whether she told a truth or a lie. "Were you sleeping in this scene?" Fallon asked. "No, in fact, I was dancing," Lawrence replied.

"I woke up and I thought it was something else, it was like normal to take it," Lawrence further explained. Oliver pointed out that she could cause a trouble for the studio if that was true, but she insisted that no one paid attention to 'The Hunger Games' franchise right now since people are focused on '

Star Wars

' movies.

Both Fallon and Oliver guessed that it was true. "It's plausible, it's reckless, I kind of like it, if it's not true I'm going to be very sad," Oliver reasoned. And Lawrence admitted that it did really happen.
