Congratulations are in order – the engaged couple and former That '70s Show co-stars, Ashton Kutcher and Mila Kunis have welcomed their first child – a baby girl.

According to the celebrity gossip website TMZ, the duo arrived at the Cedars-Sinai Medical Center in Los Angeles early Tuesday morning and Mila delivered their daughter by Tuesday night.

The couple started dating soon after Kutcher called it quits with his wife of six years, Demi Moore in 2013, and announced his engagement to Kunis earlier this year.

The Jupiter Ascending star has admitted that she never wanted to get married until she fell in love with the Two and a Half Men hunk.

"We all get movie star crushes. I'm marrying mine," gushed Kunis to wmagazine.com
