Katie Holmes? Justin Timberlake? Movieline Sorts Out the Glee Casting Rumors

Probably Not Going to Happen

· Daniel Radcliffe

The Harry Potter star recently revealed that he is excited to focus on singing, dancing and Broadway next year and would consider a small cameo on Glee, although the actor modestly added, "But, I'm not sure I'm ready for that yet. They've got standards like Kristin Chenoweth!"

· Katie Holmes

Even though the actress proved that she can shimmy and lip sync her way through a Judy Garland classic during last summer's So You Think You Can Dance anniversary episode, Holmes' publicists have repeatedly denied that she would be appearing on Fox's other dance-related show.

· Matt Lucas

Last month, The Sun reported that the Little Britain actor had landed a role as a bitter British teacher with a secret passion for musicals in the hit US TV show. It was also rumored that Lucas would sing a song himself. However, the Sun's an unreliable source, and the casting was never confirmed Stateside.

· Victoria Beckham

If Fox will let Posh Spice guest-judge an episode of American Idol, who is to say that the network won't invite her back to to add a dose of "gay icon" to Glee's second season? At least, that is what the U.K. rag The Daily Star reported in May.

· Leona Lewis

After spending a night with cast members Matthew Morrison, Amber Riley and Chris Colfer, The Mirror reported that the British singer would be joining Glee for an episode next season. Although still a rumor, the X Factor winner has already performed opposite the real-life Schue. Consider this "Over the Rainbow" duet to be Leona's audition.

· Katy Perry

During a recent interview, the pop star tried to rally her fans around a Betty White-esque campaign for a guest-star gig on Glee: "Please! I would love somebody to start that Facebook group and persuade them. I would absolutely love that." (So far, the campaign's Facebook group has just over 200 members)
