As an actor, Academy Award-winner Jennifer Lawrence has exacted ballroom choreography, affected a Brooklyn accent and gotten the crap kicked out of her without protest, but ask her to sing, and you'll usually get a big ol' N-O. Still, on last night's CONAN (July 9), she admitted there's one song that'll get her to belt.

After confessing her embarrassment over the fact that her "Hanging Tree" shot up the Billboard charts upon its feature in the most recent Hunger Games film ("I could have gone '[fart noise] hunger games!' and it would've gone to number one. It wasn't me," she laments in the clip above), co-stars Liam Hemsworth and Josh Hutcherson tell the tall-haired host that there's at least one song that'll get her on the mic.

Though J-Law admits "singing in front of people is my biggest fear in the entire world," she concedes that Cher's "Believe" allows her to push through the discomfort, and with a small cue in the clip above, she suddenly assumes the confidence of the Goddess of Pop.

"Do you believe in life after love?" Lawrence sings in Cher's famous contralto tone. Every rule's got its exception...

And that wasn't Lawrence's only anxious moment yesterday—at San Diego Comic-Con, the actress met one of her comedic heroes, Bill Murray, for the first time, and according to Vulture, was totally gobsmacked. "Like the rest of the world, I've been a huge fan of Bill Murray for a very long time," she said.
