What Baby Wants (song)

"What Baby Wants" is the twelfth track on Welcome 2 My Nightmare. The song is a duet between Alice Cooper and Ke$ha, who also wrote some of the lyrics. Cooper, who was attempting to think of who would play the devil on the upcoming album, met Ke$ha at the Grammys. His decision to perform a duet with her was done in part to surprise fans, harkening back to when Donavan and Cooper sang together on "Billion Dollar Babies".

"We wrote this with Ke$ha, who is a closet rock star... When we sat down to write this, I said this is gonna be another one of those ones where I think a lot of my audience is gonna go 'Ke$ha?!' and for me to look back and go, 'Yeah, Ke$ha.' She wrote, probably, the most disgusting lyrics in the song. Just because they're put in this pigeonhole doesn't mean that's what they are. We had to water down her lyrics. The lyrics she started with, I went, 'Whoa, woah, woah, woah... woah. Alice is too much of a gentlemen to say that.' We had a great time writing it and singing it... We got a really good performance out of her on it." - Alice Cooper
