Stepping out of Fountain Studios with a wave and a smile, Nicole Scherzinger left the first live "X-Factor" taping of the year in London on Saturday (October 6).
The former "Pussycat Doll" wore a black, one-sleeved mini-dress, with her hair pulled back as she walked to her vehicle.
During the episode, the 34-year-old singer/dancer clashed with fellow judge Gary Barlow over her choices for the final three boys.
After contestant Rylan Clarke sang Spandau Ballet's hit "Gold," Gary had some harsh words. He brashly stated, "I wanted to have some fun and I really was having fun until you started singing tonight. I was embarrassed to be sat here.'' However, Nicole quickly fired back, "Don't be an old grumpy fart."
