Remake of Promiscuous?

Tell me which one would be the best remake of Promicuous by Nelly Furtado and Timbaland:

Amy Lee (of Evanescence) & Jason Mraz
Ellen DeGeneres & Eminem
Stevie Nicks & Brandon Flowers (of the Killers)
Lily Allen & 3OH!3
Lady GaGa & Adam Lambert (from American Idol)
Paris Hilton & Boy George
Sarah McLachlan & Guns N’ Roses
Rihanna & Bryan Adams
Madonna & MGMT
Ciara & Ice Cube
Debbie Harry (of Blondie) & Jeffree Star

Just Tell me which one you would want to see, which one would most likely happen, which one is the funniest, and which one is the weirdest.
They do not get to change the Music or lyrics, just instead of Nelly Furtado and Timbaland doing, the other people will take the place. So I REPEAT: the beat, lyrics rapping and everything will be the same except different people singing it.
