Mila Kunis is said to have given birth to her first child with Ashton Kutcher.

Sources close to the 31-year-old "Jupiter Ascending" actress told TMZ that she delivered their bundle of joy Tuesday night, Oct. 1, at Cedars-Sinai Medical Center in Los Angeles, Calif.

Tipsters added that the couple arrived at the hospital at around 6:00 a.m. Tuesday and were escorted right to a delivery room. Kunis and Kutcher, 36, reportedly came by themselves with no entourage or family.

Sources told the celebrity gossip website that the actress, who has been lending her voice to Meg Griffin on "Family Guy" since 1999, gave birth right on time.

Kunis and Kutcher, who starred on "That '70s Show" as dysfunctional teen couple Jackie and Kelso, went public with their relationship in spring 2011 and got engaged back in February. News that they were expecting their first child together broke in March.

During an appearance on "The Ellen DeGeneres Show" in May, Kunis talked about how supportive the "Two and a Half Men" actor was to her. "[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,'" the Ukraine-born actress shared, according to Us Weekly.

Now that Kunis has reportedly given birth, fans are now looking forward to the wedding of the couple, who got engaged in February.

"I never wanted to get married. From the age of 12, I prepared my parents for no marriage," the bride-to-be told W magazine in an interview for its August issue. "Then things changed -- I found the love of my life. Now my theory on weddings is: Don't invite anyone. Do it privately and secretly. My parents are okay with that. They're just excited that I said yes."

"We all get movie star crushes. I'm marrying mine," she added.

This will be the first marriage for Kunis and the second for Kutcher. The "Jobs" actor was previously married to Demi Moore. They ended their six-year marriage in December 2012 and finalized their divorce in November 2013.
