Kimberly Wyatt challenged a group of celebrities to a dance-off.

The Pussycat Dolls beauty was partying at London's Studio Valbonne nightclub in the early hours of yesterday morning (September 3, 2009) when she slid onto the floor and did the splits.

Kimberly then dared former Destiny's Child singer Michelle Williams and ex-Blue member Duncan James to copy her moves.

A source explained: "Everyone was knocking back the drinks and they had a splits competition."

However, it was the 31-year-old former boy band singer who wowed the crowds with his supple limbs as he lifted his leg up over his head.

Earlier in the evening, Kimberly and Michelle discussed their career plans as they were given a glamorous makeover by UK fashion stylists Carly and Dahlia.

The source said: "The pair were so excited talking about their futures."

Meanwhile, Kimberly - who was due to fly back to the US yesterday - revealed she is so smitten with the UK, she is planning to buy a holiday home there.

She said: "I do really love London. I'm seriously considering buying a small apartment somewhere that I can stay in when I'm in town."
