There had been rumours that the star was expecting a boy, after Ashton said in an interview earlier this year that their two-year-old daughter Wyatt was referring to her “baby brother” in mummy’s tummy.

The news has now been confirmed with a message on Ashton’s website, A Plus.

It says: “A Plus is happy to announce that Dimitri Portwood Kutcher was born at 1.21am on November 30, weighing 8 pounds and 15 ounces.”

Ashton, 38, and Mila tied the knot in July 2015.
