Chris Brown
Chris Brown is one of pop and R&B's shining stars for a time, that is until he started dating Rihanna. At a pre-Grammy party in 2009, the two got in a heated fight, and Brown actually physically attacked Rihanna. She left with a split lip, lesions on her forehead, and bruises on her cheeks. Brown has never been able to recover from what he did, and his reputation is rightfully tarnished.
A Comeback?
Brown has been attempting to make a comeback, considering he was at one point the biggest name in pop and R&B. Some fans have been able to forgive him for what he did to Rihanna, but many are loyal to her and are weary that his apologies have ever been sincere. His music as of late also just hasn't been up to his original standard.
