Carly Rae Jepsen opted for a long, dark Roberto Cavalli dress and shimmery eye makeup for her very first Grammys red carpet this afternoon in LA. Carly brought her boyfriend, Matthew Koma, along for the event, and the two shared a sweet kiss as they arrived together. Carly's "Call Me Maybe" catapulted her to stardom over the past year and she is up for two awards tonight, song of the year and best new artist. Carly's pop hit showed off her fun-loving side, but she recently said that her upcoming new music will showcase some more variety — perhaps even darker material. Matthew is not the inspiration for "Call Me Maybe," but the two have been going strong since last Summer. What do you think of Carly's look?
