For years, rumors circulated about the paternity of openly gay rocker Melissa Etheridge's two children with her partner Julie Cypher.

After all, "sixty-ish," "balding," "overweight" and "history of excessive drug use" aren't exactly traits most women would look for in a donor profile. "He's musical, which means a lot to me," Etheridge explained at the time. Unfortunately, the proud parents' startling revelation was surpassed by another surprise just seven months later, when Etheridge and Cypher split up.
