The Boodles Boxing Ball charity bash was given major kudos back in 2008 when a glamorous-looking Kate Middleton arrived on the arm of Prince William.
And it's now become a high society hot ticket, with a host of royals and stars attending this year's event. And guess who was stealing the limelight (again)? Yup, Pippa Middleton, who looked amazing in a backless halter neck pleated colour block Catherine Deane gown.
Pip worked bronzed skin and makeup, and her signature half-up hairdo, and was accompanied by her suave boyfriend, Nico Jackson, dapper in a black tux.
And, it appeared, it was a right Royal knees up, with mum-to-be Zara Philips showing off her bump in a blue gown, Princess Beatrice glittering in a gold jacket, and Prince Harry looking super-smart in a fitted back suit.
Other guests included Katherine Jenkins, Kelly Brook and Guy Ritchie.
