Simon Cowell Not Hollywood's Only Serial Single

After Simon Cowell's girlfriend of six years, Terri Seymour, broke up with him over the phone, The American Idol judge's rep Max Clifford surmised the reason was that Cowell would never settle down. "In the past Terri has said that she wants kids, but that just isn't Simon," said Clifford.

We have compiled our "Top Ten Serial Singles": A-Listers who prove, again and again, that marriage isn't for everyone.
