Jennifer Lopez thinks George Clooney was an "OK" kisser.

Jennifer Lopez thinks her 'Out Of Sight' co-star George Clooney was just an "OK" kisser.

The 45-year-old singer/actress admitted she hasn't always had the best on-screen kisses and was less-than-enthusiastic about locking lips with her 'Out Of Sight' co-star.

Asked if she's had bad screen kisses, she said: "It happens. I've done over 30 movies, so the ratio... some are good, some are not so good...

"I've never had anybody with bad breath, which is good."

When she refused to name names, 'Daily Show' host Jon Stewart told her he thought George would be the worst of all, prompting her to laugh and reply: "He was OK! He was alright."

Elsewhere in the interview, the 'American Idol' judge admitted she doesn't think she would do well on the show because she hasn't got a "really big voice".

Asked if she would take part if she was a teenager again, she said: "I was so blissfully ignorant and fearless back then, now I'm afraid of everything.

"Back then, I used to do anything! I probably wouldn't have made it through. You have to have that really big voice; I have a pop voice.

"I love my voice! It's done good for me. But... some of these singers are amazing."

The 'Daily Show' interview with Jennifer airs on 'Comedy Central Extra' tomorrow morning (22.01.15) at 00:50am.
