What does Jennifer Lopez have to do with Amy Poehler's biggest fear?

During her appearance on Wednesday's episode of The Tonight Show, Jimmy Fallon challenged his guest, Amy Poehler, to a game of Truth or Truth where there are no points and everyone who gets to witness these two improvise are the real winners.

When Fallon asked the Sisters star what her biggest fear was, she gave this very surprising and hilarious response:

"Easy. Being mistaken for J. Lo. And then being asked to dance. And dancing better than J. Lo. And J. Lo being angry. I don't want J. Lo to be angry at me. That's my biggest fear."

Later in the game, Fallon mistook Poehler's "real" voice for Sofia Vergara's, which apparently is NOT one of the funny lady's fears, but definitely one of her pet peeves!
