Is this the best celebrity duet ever? The video, which surfaced on YouTube, shows the pair with drinks in hand attempting to sing along to Boyz II Men’s, “I’ll Make Love to You.” The British actor and Perry really were filmed singing the tune during a night out at karaoke club Dimples in California, a while back and at one stage, the singer pops onto the actor's lap! http://www.youtube.com/watch?v=4pmgw0m_oIw They really look like they're having a fantastic night out.
