Enjoying her time filming across the water in lovely London, England, Nicole Scherzinger arrived today (October 16) at the Riverside Studios to film an episode of TV show, "Celebrity Juice."

Looking like the sole definition of an enigma, the "X-Factor" star walked the London streets garbed in all black. From her big hat and see-through top, to her skinnies and designer heels, the 35-year-old singer looked sexy and mysterious.

In related news, Nicole seems to be enjoying her time on the small screen for her role as a judge on the UK version of "The X Factor."

Posting a photo of herself with Kelly and Sharon Osbourne, Scherzy wrote, "The third Osbourne! Love my new fam here in #London XO"
