Actor BRUCE WILLIS refused to kiss JENNIFER ANISTON on the lips when he appeared as her lover in FRIENDS - because he felt it would be a betrayal to his pal BRAD PITT.

The actor insisted on changing the scene in which he kisses Aniston, who plays RACHEL GREEN in the sitcom, and opted to kiss her on the cheek instead. He says, "I would've liked to kiss her, but Brad is a friend of mine and Jennifer's his wife. It just didn't seem appropriate, but she's a babe." (KL/US/RGS)
