Jennifer Lawrence admits to taking Ambien while shooting '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.
