18-year-old Curtis splits the panel on The X Factor 2012 tonight.
The self-confessed geek from Derbyshire performs a unique take on Candyman by Christina Aguilera for the panel as auditions move to Manchester with guest judge Mel B.
Louis and Tulisa are both impressed with the performance.
Louis gushed: "I didn’t know what to expect, you’re quirky and you’re different, but you remind me a bit of Peter Kay – in a good way, I think you’ve definitely got something."
Tulisa added: "I think we’ve got a nerd that is very talented"
However a grumpy Mel B moaned: "I found it all a little bit irritating, the overdoing the comedic personality thing, I found that irritating."
Tune in to the X Factor auditions tonight to see if Curtis makes it through.
