One-time pop-star Paris Hilton is a good singer - according to the co-stars of her new movie. The star's eponymous 2006 album failed to win over the critics, but Repo! The Genetic Opera choreographer Tre Armstrong insists the socialite impressed him with her vocal prowess. He says, "I was surprised that she could sing. Honest to God, I will never crack on Paris. I haven't. From what I hear from what they did, I like how she sounded." And Armstrong isn't the only one praising Hilton's talents - R+B star Keyshia Cole, who appears alongside Hilton in Repo!, adds, "I like the way she sings. I do."
