It's official, Mila and Ashton have named their baby girl Wyatt Isabelle Kutcher. Known for his quick wit and teasing sense of humour - how could we forget the Punk'd days- Ashton broke the news via his website with a series of pictures and this little note; 

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

It's time to place your bets (we're backing number one). 

We believe congratulations are in order for Mila Kunis and Ashton Kutcher, who have welcomed a baby girl into the world.

According to reports, the baby was born on Tuesday at Los Angeles’ Cedars-Sinai Medical Centre, and as it stands, no name has yet been revealed – which isn’t surprising, considering the couple have been adamant about keeping the pregnancy (and their relationship) very much under wraps.

The pair first met on the set of That ‘70s Show 16 years ago, and announced their engagement in February earlier on this year.

It's been a long time coming… Could a wedding be next on the cards? 

We've already cracked open the champagne.
