In a surprise jolt to tonight’s American Idol finale between David Cook and David Archuleta you can expect to see performances from Miley Cyrus and the Jonas Brothers.

Idol producer Nigel Lythgoe called into Ryan Seacrest’s morning radio show to give some hints as to what to expect in Tuesday night’s finale between the Davids.

Other hints included appearances by “some young brothers” and “the biggest star in the world right now,” Lythgoe said.

That clue is not too hard to decipher. No one is bigger in the music world than Miley Cyrus right now. And when you see Miley the Jonas Brothers aren’t too far behind either.

The additions of Miley and the Jonas Brothers to the show is guaranteed to bring millions of more teens to watch.  This will be a very decided advantage for teen favorite Archuleta.  Is this a strategic move by the producers of the show to guarantee a win by Arch Deluxe?

Cook and Archuleta will each sing three songs during the show. The first song will be selected by industry legend Clive Davis. The second song will be selected by viewers of the show via an online poll. And the final song will be chosen by the contestants. It could be something new or something they have already performed on the show.

So who is going to win the battle of the Davids? Vote below!
