Singer/songwriter Chris Brown is is not perfect, and he's man enough to admit he is flawed.
Brown was involved in a long-term relationship with his then-girlfriend Karrueche Tran when he knocked up a groupie during a one night stand.
Karrueche might have forgiven Brown (for being a man) if it weren't for the fact that the groupie -- Nia Guzman -- was her best friend.
