"And then she points to dad and she goes, 'Beer,' so I think she gets there's something in the belly but I don't quite think that she knows that it's not going to be a plastic doll yet.”

On Wednesday night Ashton had appeared on ‘The Tonight Show With Jimmy Fallon’ and revealed how little Wyatt celebrated her second birthday earlier this month.

When asked if he’d done the ‘theme’ party yet, Ashton said: "We just had this second birthday party: 'Peppa Pig'.

“Peppa is the real deal,” he added of the popular British cartoon. “We don't make anything in America anymore.

"It's like these English pigs. They couldn't dub them with American accents. Peppa's the business, though. We walk around the house talking in the accents. 'Muddy puddles,' ‘Dinosaur,' 'Brudda George!’”
