Paris Hilton attended the screening of her new movie “Repo! The Genetic Opera” in Las Vegas where she was accompanied by her boyfriend Benji Madden who showed just how proud he is. Paris was glowing in a shiny silver and black strapless minidress teamed with a pair of sliver heels and a black handbag. And as for the movie, it’s getting some fairly nice reviews with one critic standing out stating, “Straight bloody, futuristic fun with a musical twist, Repo! will no doubt find its niche.”
