Gangnam Style by Britney and Mel B

"Gangnam Style" (Korean: 강남스타일, is a single by South Korean rapper Psy. The song was released on July 15, 2012, as the lead single of his sixth studio album PSY 6, Part 1. "Gangnam Style" debuted at number one on the Gaon Chart, the national record chart of South Korea. As of October 17, 2012, the music video has been viewed over 480 million times on YouTube.

Last month, Britney Spears from X Factor USA performed with the K-pop phenomenon during an appearance on the Ellen Show.

Thousands of fans swarmed the programme's Martin Place studios in Sydney to catch a glimpse of Psy—and Mel B was on hand to dance with him after viewers picked her as the X Factor judge they most wanted to go Gangnam Style.

Former Spice Girl Mel B performed Psy's Gangnam Style dance with the Korean superstar on X Factor Australia on Tuesday, revealing that her daughter would have killed her if she turned down the opportunity. Mel B admitted she was under pressure to perform, saying, "My daughter will kill me if I don't do this."

She added, "My daughter said she'd cook me breakfast in bed on Friday (if I did this)," and then she turned to Psy and cooed, "I have to say you are a legend. I do feel honoured."

Mel B is the second X Factor judge to dance with Psy on TV.
