This weekend, Beck played to developers at Yahoo Hack Day, in a fantastic little concert on the Sunnyvale campus, making him the second celebrity Scientologist known to visit the Yahoo campus, after Tom Cruise's visit earlier this year.

So who's next? Kirstie Alley? Jenna Elfman? Earthlink chief Sky Dayton? Here, browse the list of celebrity Scientologists and take a guess in the comments. Tip: Say more than a name. Be clever, readers!
