Red Hot Chili Peppers' bassist Flea (Michael Balzary) has bright purple hair!  We spotted the musician chatting on his phone while he took a walk in Soho with his daughters Clara Balzary and Sunny Bebop Balzary yesterday.

He's not the only music star who likes jazzing up his hair.  Rihanna has been a bright red head for quite a while, and Katy Perry has experimented with blue hairstyles.

Nicki Minaj is one of the most outrageous colored hair trendsetters. She has a penchant for pink. Check out photos below:
