Matt LeBlanc and Melissa McKnightThe “irreconcilable differences” that Matt LeBlanc is citing in his impending divorce from his wife Melissa McKnight may not be as innocent as just growing apart or the like.

People magazine is reporting that Matt is already romantically involved with Joey co-star Andrea Anders and that is the cause of the split.

Matt unexpectantly moved out of the family home in January and a few weeks later, when Melissa accused him of seeing another woman, Matt confirmed that he was.

A long term friend of Melissa’s, Kelly Phillips told the magazine: “It was very sudden. She was absolutely blindsided by what transpired.”

Another friend confirmed that Melissa had wanted try all the alternatives before the Anders revelations came to little: “She wanted to do counseling or therapy but Matt just didn’t want to work it out.”
