A little self medication! Jennifer Lawrence revealed that she once took an Ambien pill before shooting a scene in her Hunger Games movie franchise!

The 25-year-old actress made the hilarious revelation during a game of True Confessions with Jimmy Fallon and British satirist John Oliver on Monday, May 23.

The actress sat round the table with the Tonight Show host and her fellow competitor to answer questions relating to her first potential confession.

"I once took an Ambien before filming a scene in The Hunger Games," she announced before Fallon and Oliver were tasked with figuring out if she was telling the truth.

"Were you sleeping in the scene?" asked Fallon.

"No, in fact I was dancing?" she responded. "I thought it was something else that was like, normal to take."

"It's plausible," pondered Oliver. "It's reckless, I kind of like it," he continued.

In the end both he and Fallon decided Lawrence was telling the truth.

"It's true!" she admitted, holding up her hands.
