Walliams Baby 'Looks Like Si-Co' - Amanda Holden

Amanda Holden has joked that David Walliams' new baby looks like Simon Cowell.

The Britain's Got Talent judge questioned the parentage of her colleague's firstborn during an interview with Alan Carr on his Chatty Man show - set to be broadcast this evening.

She has the cheeky theory that SiCo and D-Wal mixed up their seed in order to become "joint dads".

"I said he looks more like Simon," Holden told Carr.

"They're going to make brilliant dads. I think they put it all in a test tube, gave it a little shake and Lara took it."

And she continued her off-colour quips with an explanation of her previous claim that Cowell goes commando.

"He stood up, sorted himself out and I saw it dangling. I could almost tell what religion he was," she said.

"I said, 'Darling, have you got knickers on?' He went, 'No, darling - I love to go commando. I like to be free'."

David Walliams and wife Lara Stone welcomed their first child to the world on Sunday.
