It's official - Kelso and Jackie have a little girl!

Little did we know when we we're typing "yes, she's still pregnant" in yesterday's article chronicling just how helpful Demi wanted to be with the baby that Kelso and Jackie already had their mitts on their liddler.

The Black Swan actress, who started dating her former That 70s Show co-star in 2012 and got engaged to him earlier this year, is said to have given birth to a baby girl at Cedars-Sinai Medical Centre in Los Angeles on Tuesday night. 

A source close to the couple told TMZ that the couple were taken straight into the delivery room after arriving at the hospital at 6am on Tuesday morning.

The insider said they arrived alone, without any family members or assistants.

It was recently revealed the 31-year-old actress was tired of waiting for her daughter to arrive and was getting desperate to go into labour.

Another insider said: "Mila just wants the baby to come out already! Mila hasn't slowed down at all. She seems to have a lot of energy." Well, that's what happens just before you give birth - you get lots of energy to get all the last minute jobs done that you'll never get round to completing once your bundle of all-consuming joy arrives. 

The couple were reportedly disappointed that Mila didn't go into labour while Ashton was on a break from filming Two and a Half Men last month.

A friend said at the time: "They were hoping the baby would come this week because he's on hiatus. He is a nervous wreck."

Ah, celebrities. Despite what you think, you can't dictate to Mother Nature.

According to Us Weekly, Kutcher's twin brother Michael told the magazine that the new parents were "meant to be" at the Harboring Hearts 2nd Annual Summer Soiree in NYC. "It'd be like Ross and Rachel getting married." Really he could've said "It'd be like Kelso and Jackie getting married", may have been more fitting, but he's obviously more of a Friends fan.

Speaking of getting married, Mila previously said something that will melt many hearts this morning: "I never wanted to get married…then things changed - I found the love of my life... We all get movie star crushes. I'm marrying mine."
