2. Dr. Dre
He may be likable now thanks to Beats by Dre (& that damn Dr. Pepper commercial), but it wasn’t too long ago that Forbes’ second-richest rapper in the world was known strictly for his “gangsta” rap thanks to his affiliation with NWA & Death Row Records. And he lived up to his name when, in 1991, he encountered rapper & TV host Dee Barnes at a party. The Doctor, apparently feeling that Barnes wronged NWA for an interview with Ice Cube that was perceived as “negative” by the group, “began slamming her face and the right side of her body repeatedly against a wall near the stairway,” according to the lawsuit. Though Barnes sued Dre for $22.75 million, Dre pled it down to a fine, community service, and an anti-violence PSA.
