Britain's Got Talent judge and funnyman David Walliams has admitted that he once kept supermodel Kate Moss waiting backstage so that he could meet Beatles legend Paul McCartney.

The 41-year-old star was touring his Little Britain stage show with his writing partner Matt Lucas when they were told Moss had attended a performance with her then-boyfriend, musician Pete Doherty.

However, Walliams decided to keep the 39-year-old Rimmel model waiting backstage after realising that the Beatles icon was also in the building.

Speaking to Event magazine, David said: "One night Matt and I were doing Little Britain live. We heard MCCartney was in the audience. And Kate Moss. It's one thing meeting someone at an event, but for someone like that to come and see you... You don't think people like that actually watch TV.

"He came backstage and was really sweet and it was this amazing golden moment. But we had to keep Kate Moss and Pete Doherty waiting. We had to make a decision. Who did we think was more important and we went, 'The Beatle one!' He has to come first. We are not going to say, 'We're sorry Paul, Kate's here.'"
