Nicole Scherzinger stepped out from behind the judging table and hit the stage on ‘The Sing-Off’ last evening. The singer performed Diana Ross’s classic ‘Ain’t No Mountain High Enough’ alongside The Persuasions. Check out the performance below:

With the exception of Scherzinger’s screaming, that was a solid performance. It baffles me that as such a talented vocalist that she would consider that amount of screeching to be musical in any way. She can do, and has done, a lot better.

Thoughts?
