They've both enjoyed huge success as judges on Britain's Got Talent, but according to Simon Cowell, David Walliams was very nearly not a part of the show.

In fact, Cowell said that the first meeting he had with the comedian and actor in relation to taking part in the show was 'one of the worst meetings [he's] ever had'.

"I do remember the first time I ever sat down with him," he said on ITV's Lorraine this morning. "He came into the dressing room while I was doing X Factor, and I pitched him the show. We had one of the worst meetings I’ve ever had. When I say it was bad, it was bad. And I thought, 'this is never gonna happen'."

However, a year later Walliams changed his mind.

"Then a year later we had another conversation and he agreed to it," Cowell confirmed. "To be fair, he and the show are a perfect match."

The new series of Britain's Got Talent airs this Saturday at 8pm.
