Possibly inspired by the late rapper Tupac, Rihanna recently toughened up her look with a series of tattoos spelling "THUG LIFE" across her fists. The 23-year-old Pop singer went to a tattoo parlor in Los Angeles on Jan. 24, 2012, and tweeted out photos of herself getting the new body art, writing, "All these b----es screaming that 2pac back" and "I #LOVE my new tattoo!!!"
