James Arthur’s mentor fails to put a foot wrong in The X Factor style stakes

Nicole Scherzinger went out on a high for The X Factor final with a pair of killer knee-high leather boots.

The former Pussycat Doll wore sexy heels by Lebanese designer Karen El-Khazen, who has a label called Karen K and can be found at www.karenkboutique.com.

The hot, limited-edition boots have a built-in suspender strap to hold them in place and cost a whopping £1,635.

Scherzy combined the boots with a sexy LBD from Gareth Pugh for her performance with X Factor winner James Arthur.
