PM: Walliams is Sam Cam's favourite
David Cameron joked that his wife's favourite David is one of the stars of Little Britain as he hosted a Downing Street reception to celebrate Wales's national day.
The Prime Minister said Samantha Cameron claimed David Walliams was "the funniest man she'd ever met" as he addressed nearly 100 guests at Number 10 for St David's Day.
Business leaders, sports stars, politicians and television personalities attended the event, including former Paralympic athlete Baroness Tanni Grey Thompson, Songs Of Praise presenter Aled Jones, stage star Connie Fisher and Gabby Logan, whose father Terry Yorath managed and played for Wales's national football team.
Mr Cameron said he was "delighted" that staff from Welsh newspaper the Western Mail were among the guests after asking their readers to name their favourite David.
"I don't know how I'm getting on," he said. "All I know is that Samantha admitted to me the other day that her favourite David is David Walliams, which I thought was slightly disappointing as she's married to me.
"She sat next to him at a charity function and said he was the funniest man she'd ever met so I'm going to have to learn to live with that."
Mr Cameron said he had been researching his family history and his maternal grandmother's name was Llewellyn and her grandfather was a tin plate maker from Glamorgan called Llewellyn Llewellyn.
"I think that's real Welsh heritage," he said.
Mr Cameron said the "industrial future" of Wales should be celebrated and "not just the great and proud past", as he named Airbus - which employs 6,000 people at its site in Broughton, North Wales - as one of the country's economic successes.
