Mariah records with heavyweights

Mariah Carey is making sure her next album is a big hit by signing up heavyweights like The Neptunes, Jermaine Dupri, Kanye West, R Kelly and Snoop Dogg to work with her on new tracks.

Producer Dupri was so impressed with one track on the new album, called Can I Get Your Number?, he agreed to duet with Carey.

He says: "Mariah is singing unlike we've heard her in a while. She is hot."
