Jennifer Lawrence gave a strong, definitive answer when a caller on "Watch What Happens Live" asked whether she would hook up with Justin Bieber.

"I'm going to say a hard no," Lawrence said on the Bravo talk show hosted by Andy Cohen, "but thanks."

Last month, Bieber described his "Hunger Games" celebrity crush as "so sexy" and "so cute" during an interview on Capital FM. He also said he would "bae it up" with Britney Spears and Rihanna.

Cohen followed up the Bieber call with another relationship question for Lawrence about dating Coldplay frontman Chris Martin. She confirmed to the host that they never stated publicly whether they were together or not.

So were they officially a couple?

"Come on," Lawrence chuckled, avoiding the question.

The Oscar-winning actress is back in theaters this weekend with her new movie "Joy," while the last installment of "The Hunger Games" continues its box office success.
