The 38-year-old actor dotes on 18-month-old Wyatt - whom he has with his wife Mila Kunis - and can think of nothing better than being a father.

He gushed to E! News: "It's legitimately the greatest thing ever."

Ashton is also excited about his latest venture, new Netflix series 'The Ranch', in which he stars alongside former 'That '70s Show' co-star Danny Masterson, and the two actors can see a lot of similarities between their new characters and their former alter egos.

Ashton - who plays failed semi-pro NFL player Colt - said: "I think the magic thing is it has that same feeling of a couple friends hanging out or a couple brothers hanging out."

And Danny - who portrays his brother Rooster - added of the series: "It's usually Hollywood making fun of Middle America and we wanted to be Middle America making fun of Hollywood."

Ashton recently admitted he doesn't let his young daughter eat sweets so gave her a toy egg filled with raisins for Easter recently, rather than traditional chocolate treats.

He said: "We didn't want to put candy in [her Easter basket] because she's one-and-a-half and she's not quite ready. We're not quite ready for her to be ready for candy, so we did Cheerios and raisins. She loved the raisins!"
