K-Fed was engaged to that other woman, had already had a child with her, and the other woman was like 6 months pregnant or something with their second child. Then he left her for Britney.
If some guy wanted to leave his fiance and two babies for me, I wouldn't touch his ass with a 10-foot pole. Once a cheater, always a cheater. Really.
I heard Brit's mama made her get a prenup. Good for her lol.
