Rumor Mill: Anthony Kiedis Got Some on the Side

Sources tell OK! that Red Hot Chili Pepper frontman Anthony Kiedis, 44, may not have been the best boyfriend while his girlfriend, Heather Christie, 21, of two years was pregnant with their kid.

Rumor is that while in a Malibu AA last year to kick drug and alcohol addictions Anthony began an affair with one of the other members of the group, who he allegedly didn't even tell he had a girlfriend, let alone a pregnant one.

"He has screwed my friend over so many times, but she's so in love with him that she won't do anything about it," the source tells OK!.

When contacted a rep for Anthony said, "TKTKTK."

Anthony and Heather had their son Everly Bear in October.
