Well, we heard about Steven Spielberg contacting her, and now apparently Tom Cruise and Katie Holmes have also taken a shine to American Idol loser Katherine McPhee. Scuttlebutt in the gossip rags has it that McPhee met Holmes at the Church of Scientology in Los Angeles, and the two hit it off, swapping tips on how to smile and look cute, or whatever the hell they talked about. Anyway, the (in)famous Hollywood couple known as TomKat have apparently asked McPhee to perform at their wedding. The song she'll be singing is "Garblax, Tyranical One-Eyed Ruler of the Gleeferslock Galaxy." Or possibly, "You Light Up My Life." It's often hard to tell with this kind of ceremonies.
