#3 – Chris Brown
Chris Brown was already at the peak of his career when his love life issues took over his music. For a time, Chris Brown and Rihanna were the music world’s favorite loveteam. It is a love story turned bitter when Rihanna appeared on public confirming that she was physically abused by her beau. Of course, the public will sympathize with the lady. It affected Chris Brown’s career and even if they tried to reconcile by recording a number of duets, there’s no doubt that it tarnished his then blooming career.
