Is this an early holiday present or what? Katy Perry will be hosting SNL on December 10! She'll be finished with her "California Dreams" tour (122 dates) and possibly her last performance before her temporary break from show biz.

While we haven't heard who would be the musical guest, could Katy be doing double-duty? We're totally excited about this. Will she wear her cupcake bra? Will she do another duet with Elmo? 

Will hubby Russell Brand make a cameo appearance? Inquiring minds want to know! Guess we'll have to wait until Saturday, December 10 at 11:30 pm ET to find out!

Tell us: Who do you think would be a cool musical guest for the show?
