Ashton Kutcher will be a 'tough' father

ASHTON Kutcher's twin brother thinks he'll be a strict father.

The 'Two and a Half Men' star is expecting his first child with fiancée Mila Kunis later this year, and Michael Kutcher has no doubt they're ready to start a family together.

He said: "They're going to be great parents."

The 36-year-old actor already has a lot of experience with children and is an "amazing" uncle to his nephews because he's "full of energy".

Michael added: "He never wears out. He always goes, goes, goes."

He also predicted that Ashton and 'Black Swan' star Mila, 30, who are rumoured to be expecting a daughter, would "maybe [be] a bit more protective" of a baby girl than a boy.

But he added: "[They are] going to be able to set the right discipline in their child - sometimes you have to be tough!"

Michael and Ashton are still extremely close and the actor was by his twin's side when he had to undergo a heart transplant when they were 13.

He told E! News: "I think it brought on the value of each day-- how much we all cherish each day.

"To this day, if I'm texting my brother, the last thing one of us will say is, 'I love you. It's so important. And it's not just heart disease. You can go outside and get hit by a taxicab. It's the reality of life. It's so short. You've got to enjoy every single moment."
