was on a roll Wednesday night – showing off her skating moves at a charity bash in London.
In a green sequined halter top and yellow hot pants, Middleton, 26, co-hosted an day-glo disco
at London's Renaissance Rooms with a group of friends in a bid to raise $200,000 for a children's hospital ward.
Tom's Ward at the Children's Hospital in Oxford, England
was set up in memory of Middleton and Prince William
's close pal Sam Waley-Cohen's brother, Thomas, who died in 2004 after a battle with cancer.
"We wanted to do something fresh and new; something that would be fun and a bit tongue-in-cheek reflecting the lighter side of life; very much like Thomas was himself," Sam Waley-Cohen said in a statement.
Middleton, who helped organize the bash with Waley-Cohen and Holly Branson – the daughter of Virgin Airlines tycoon Sir Richard – definitely reflected fun, moving around the party, in her skates that lit up, with a tray of donuts.
Also taking to the floor was Kate's younger sister Pippa, who matched her sister with pink leg-warmers, and Fergie's daughter, Princess Beatrice, 20, who wore a red Mohawk wig. Prince William, though invited, was not in attendance.
Also benefiting was The Place2Be
, which provides counseling to 43,000 children and their families in 130 schools. RELATED ARTICLE:
