CBS is enacting its first Charlie Sheen contingency plan: The network ordered two more episodes each of 'Mike & Molly' and 'Rules of Engagement' to help deal with any issues arising from the 'Two and a Half Men' star's absence, according to The Hollywood Reporter.

Sheen began rehab this weekend after being hospitalized in the wake of a reportedly very wild party with some porn stars at his home. 'Two and a Half Men' went on immediate hiatus. THR reports that Sheen will be unable to work for three months while he undergoes treatment.

This may be the guest role that Neil Patrick Harris was born to play. The actor has already shown off his musical chops on Broadway, starring in 'Cabaret' and 'Sweeney Todd,' to name just a couple of shows. Now, he gets to appear on 'Glee' (Tue., 9PM ET on Fox).

[Spoiler alert.]

Last week on his show, Jay Leno said he thought that he might be related to singing sensation Susan Boyle because his mom is from Scotland. He then showed this. Half of me wants to say ha-ha (though it's not really funny), the other half of me wants to punch Leno for dressing up like Boyle because he thinks they might look alike. (I also continue to be irritated that people are "amazed" that Boyle can sing - what, she's not Hollywood beautiful so the judges and audience didn't think she had talent?)

Also, that guy backstage...is that Kirk Cameron?

Well, Andy Warhol said everyone gets 15 minutes of fame, but has Susan Boyle's quarter-hour already expired? That's the opinion of New York columnist Michael Musto, but I think his Rolex knock-off is running fast. Musto thinks Boyle is done, but, you watch, Susan will be around for at least another week or two.

She was on Larry King Live on Friday. There's rumors that she's going to appear on Oprah, and I wouldn't put it past American Idol and Simon Cowell to spring her on us, giving 20 million Americans a chance to be amazed by her sweet voice and reviled by her hairy eyebrows.
