Nicole Scherzingers' covers Adele's "Rolling in the Deep" with mixed results.

The newly appointed X-Factor (USA) co-host Nicole Scherzinger decided to show all just why she deserves to be upgraded to a coveted place on the judging panel- if reports that Cheryl Cole has been given the boot are to be believed- by giving a solid performance of Adele's Billboard number 1 hit Rolling in the deep.

Nicole's vocals are solid throughout but take a dip in quality when attempting the higher belts of the chorus. Though the singer does manage to hit the notes, unfortunately there's a tradeoff in the decline of the vocal quality and her voice becomes harsh, pushed and unpleasantly overbearing.

However, that's a minor quibble, and overall Nicole managed to give a great performance of an exceptional song!
