tomkat.jpgTom Cruise and Katie Holmes have asked American Idol runner-up Katharine McPhee to sing at their wedding. According to sources, “Actress Holmes reportedly met McPhee at Los Angeles’ Church of Scientology, where the singer allegedly attended courses with her boyfriend, and has since become a huge fan.” McPhee is expected to sing her now famous cover of Somewhere Over the Rainbow from the Wizard of Oz. I guess Tom’s just really big fan of Dorothy.
