According to sources, Mila gave birth right on schedule.

The baby girl is the couple's first child.

Kunis and Kutcher have been publicly dating since spring of 2011. The two got engaged earlier this year in February and confirmed the pregnancy in March.

Unlike a lot of celebrity mom-to-be's, Kunis proudly showed off her growing baby bump all throughout the duration of her pregnancy. She apparently craved for frozen yogurt and burgers, which the paparazzi confirmed after they were photographed at several Dodgers baseball game in Los Angeles and were seen having fun at a music festival in Indio, California.

Kunis also dished on how supportive her fiance was with her pregnancy with Ellen Degeneres on "The Ellen Degeneres Show" last May. She said that Ashton "assumed that I was gonna have goofy cravings, so he stocked our secondary fridge with weird food -- just, like, pickles and sauerkraut, or, like, anchovies and ice creams -- just in case at one point during this pregnancy I'd be like, 'I really want something.'"

Kutcher confirmed that he indeed stocked their fridge right because Kunis did indeed crave for pickles and sauerkraut the most.

The two are definitely happy together, and Kutcher's twin brother Michael attests to their happiness. According to Michael, the two were meant to be, likening the two to the famous on-screen couple Ross and Rachel from "Friends".

Michael Kutcher said that Ashton is in a really great place and that the two, who co-starred in "That '70s Show" and played on-screen couple Jackie and Kelso, make such a great couple.

While there are no concrete details about their upcoming wedding, it will be the first for Kunis, while it would be the second for Kutcher. Kutcher was previously married to Demi Moore for six years until they split in December 2012. The two have finalized their divorce November last year.
