American Idol winner Jordin Sparks is set to appear on R+B singer Tank's new album - after impressing the star during an impromptu jam session. The pair performed together during a break from selecting outfits at the Grammys Style Studio - the awards gifting suite - on Friday (08Feb08) when Tank, real name Durell Babbs, began playing on a piano. Babbs coaxed Sparks to sing with him, with the pair improvising a track with the chorus "I don't ever want to lose you", and she sang the new tune for three minutes. And the Grammy-nominated star is so impressed by the star's singing talents, he is desperate to have Sparks appear on his forthcoming album. He says, "She's been recruited."
