"You're gonna hold up, on your head, pictures of famous Jens," Ripa, 43, explained. "I'm gonna give you hints and you're gonna guess who they are!"

"Well, we'll see about that last part," Lawrence, 23, responded, as she held the first Jennifer up to her head. "K, she's everybody's favorite friend," Ripa hinted.

"Jennifer Aniston," the X-Men: Days of Future Past star responded without skipping a beat. "As soon as you said 'favorite,' I said 'Aniston!'"

Ripa continued to rattle off a list of other famous Jennifers including Flashdance actress Jennifer Beal, Idol Judge Jenner Lopez, and "she's uh, married to Ben Affleck."

"Jennifer Garner, god!" yelled Lawrence. "I am killing it!"

Oscar winners Jennifer Connelly and Jennifer Hudson were also mentioned, as well as "middle name is love" Jennifer Love Hewitt, and "she's from the Jersey Shore" Jenni "JWoww" Farley.
