Nicole Scherzinger "who needs sleep"

Nicole Scherzinger has jetted in from the States to perform at this year's Summertime Ball before dashing back for The X-Factor"

But Nicole's not daunted by the jet-set weekend, "Who needs sleep. When I perform I like just like to leave it all out their on the floor. Our dancers are amazing and really excited to do my single, Right There. It will be full throttle. Hopefully people are going to be sweating and feeling good" 

After her performance Nicole will be jetting back across the Atlantic to continue The X-Factor auditions and she admits it's been a tricky time after moving from presenting to judging, "I was incredibly nervous but everyone on the panel are good people...I am really truly honoured to be a part of the panel".

No mention of the C-word though!
