Amanda: David's baby like Simon!
David and wife Lara Stone welcomed their new arrival last week, and Amanda said that when the Little Britain star sent her a snap of the newborn she thought he resembled the TV boss, reported The Sun.
She joked on Alan Carr: Chatty Man on Channel 4: "I said he looks more like Simon.
"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."
Amanda also dished about Simon's toilet habits during her chat on the show, explaining that the mogul is never far from his mouthwash.
She said: "We always get designated a judge's toilet for BGT. Simon keeps a little bottle of Listerine in his.
"There are also weights - I think he gargles and lifts at the same time."
