On And Poppin'! Chris Brown's 10 Greatest Beefs
His Opponent: Raz B
Why They Were Beefing: In late 2010, Raz B jumped on Twitter and asked how guys like Eric Benet and Chris Brown could disrespect beautiful women like Halle Berry and Rihanna. CB struck back almost immediately with a stream of remarks about Raz B's alleged molestation during his B2K days.
The Result: Raz B's brother Ricky Romance eventually got involved in the beef and went as far as to physically threaten Chris Brown's well-being. But in the end, Raz apologized for taking things too far and said he hoped "someone learns something valuable" from the beef. Yeah, we learned that CB checks his "@" replies—often!
