Pop star Nicole Scherzinger would never challenge Britney Spears to a dance-off, because she's scared she'd be humiliated by the Toxic hit-maker's moves.

The Pussycat Dolls are currently supporting Spears on her North American tour - and while both artists perform energetic routines during their sets on stage, Scherzinger insists her skills are nothing compared to Britney's.

She tells MTV.com, "I would be afraid (to challenge Spears). She can throw down. She's got some moves. If we had a dance-off, maybe it would be more of a collaboration dance or maybe one of the other girls can do it; I'll just stand and watch. She's a great dancer and a great performer."
