Nicole Scherzinger wore a sexy, skintight catsuit during a night out in London on Tuesday. The ensemble included criss-cross cut outs on the sides of her body, exposing major skin.

The peek-a-boo design proved that the U.K. "X Factor" judge wasn't wearing any underwear. She paired the look with simple black pumps and wore her hair down in loose waves.

The former Pussycat Doll, 35, was recently being spotted meeting with her her ex-boyfriend Lewis Hamilton at a London hotel, but the couple haven't rekindled their relationship. She told The Sun newspaper they are "just friends."

"A lot of time in relationships people lose themselves - they lose that sparkle, that shine, their purpose and how 'schmazing' they can be. For me, I had to get back to my core, my center, my soul," she explained.
