Alice Cooper recently revealed that he cast Kesha as the Devil in his new song, 'What Baby Wants,' and now a new clip showcases the pop star's wicked vocals on the 'Welcome 2 My Nightmare' track.

“I’m gonna drain your veins and bathe in your blood,” the 24-year-old sings. The clip gives fans a sneak peek into a split verse and chorus from the rock duet.

The collaboration isn't entirely out of left field. Cooper tells Ultimate Classic Rock, “Kesha’s an old friend of mine. When she was in London, I got up and did a song with her. She actually plays the Devil in this thing.”

The song is a conversation between the two stars in which Cooper tries to outwit his adversary. “When she decides that it’s time for her to get paid — you know, there’s always that ‘I need your soul now’ kind of moment — and I’m trying to talk my way out of it, she goes ‘Oh no no no, what baby wants, baby gets.’ That’s the song — ‘What Baby Wants.’ I wrote it with her and Bob Ezrin and the song is very cool.”

The idea for Cooper's soon-to-be-released album came about shortly after the thirtieth anniversary of 1975's 'Welcome to My Nightmare.' 'Welcome 2 My Nightmare' is the rocker's 19th solo LP, arriving on Sept. 13.
