David Walliams is being blamed for the break up of a marriage.

Although his name is masked by the words "an affair with a well-known public figure", the Little Britain co-creator is reportedly the man to blame for the split between Czech underwear model Petra Coulson and her husband.

Coulson, who admits keeping her marital status to herself at the time, is said to have had a two-night stand with womanising Walliams after meeting him at the 10th birthday party of Agent Provocateur.

"I rang David to tell him he was being referred to in my divorce papers but he thought I was joking," Ananova.com quotes her as saying.
