Mila Kunis and Ashton Kutcher have named their baby daughter Wyatt Isabelle Kutcher.

Ashton, 36, made the announcement on his website yesterday (02.10.14) and added that he hopes the tot's life - who was welcomed by her parents earlier this week - will be filled with ''wonder'', ''love'' and ''privacy''.

He wrote: ''Mila and I would like to welcome Wyatt Isabelle Kutcher to the world. May your life be filled with wonder, love, laughter, health, happiness, curiosity, and privacy.''

The 'Two and a Half Man' star also uploaded multiple shots of newborns asking fans to guess which of the babies was their own.

He joked: ''Can you guess which one is ours, or does it really matter? All babies are cute.''

Mila, 31, and Wyatt are said to be ''healthy and happy'' following the birth at Cedars-Sinai Medical Centre in Los Angeles.

A source close to Ashton and the 'Black Swan' actress - who started dating her former 'That 70s Show' co-star in 2012 and got engaged to him earlier this year - confirmed news of the birth, saying: ''She's here and healthy.''
