Little Boots and Kelly Osbourne hung out together along with Kimberly Stewart at the Nokia Skate Almighty VIP launch party.
Just as the roller disco was starting, Boris Johnson did a slow cycle by the Potters Fields bespoke outdoor skate rink, which is right by the Mayor's headquarters, at Tower Bridge.
Rod Stewart's daughter, Kimberly who wore some killer heels didn't manage much skating, while Ozzy Osbourne's daughter, Kelly, preferred to show off her new bleached hair and was seen planting kisses all over her boyfriend Luke Worrell, who arrived shortly after her.
But the American actress Margot Stilley, who starred in the controversial and sexually explicit 2004 film 9 Songs directed by Michael Winterbottom, skated the night away while the Foals did a DJ set.
Little Boots, whose real name is Victoria Hesketh, changed into a striking green and blue mini dress and wore a super cool hat as well as high gladiator ankle boots when she took to the stage. She performed a 30-minute live set to the 600 guests and the roller disco came to a halt.
The free event for the public continued over four nights, giving thousands of skaters a chance to skate to live performances and DJ sets from acts including Queens of Noize, Calvin Harris, The Holloways, The Pipettes and Goldierocks.
