One of the most anticipated guests of the evening, Rihanna was spotted arriving at the 53rd Annual Grammy Awards in Los Angeles earlier tonight (February 13). Always a fashion trendsetter, the “Russian Roulette” hitmaker looked amazing as she hit the Staples Center red carpet. Rihanna’s ex-boyfriend Chris Brown will also be in attendance tonight, though he’s required by a restraining order to stay plenty far away from her. Back in 2009, Chris ended up beating Rihanna after an argument following a pre-Grammy shindig.
