Simon Cowell got dumped by his longtime girlfriend, Terri Seymour. Simon's rep told People,

"Terri phoned Simon and finished it in September, about six weeks ago....They are going to remain close friends. Simon thinks the world of Terri and that isn't going to change. He also understands her reason for ending it....In the past Terri has said that she wants kids but that just isn't Simon."

If they had children, Terri would have three kids on her hands...the baby, Simon and his ego. Smart move Terri.
