Congratulations to Mila Kunis and Ashton Kutcher! According to TMZ, the couple welcomed their first child, a baby girl on Tuesday. Mila was said to give birth at Cedars-Sinai Hospital in Los Angeles.

The site added that the couple arrived at Cedars-Sinai Hospital in Los Angeles at 6am and were taken immediately to the delivery room.

"That 70's Show" co-stars, who got engaged in February, have stayed mum about pregnancy details. However, Mila did share a bit of information on her birthing plans in the July issue of Marie Claire.

"Two people are allowed in my delivery room. My doctor and my significant other," she said. "And he [Ashton] is staying above the action. He'll be head to head. Not head to vag. Unless he wants to risk his life and see. But I wouldn't if I were him. I highly doubt he wants to see that being ripped apart and shredded. Because it will be shredded. It's just a matter of how badly."

Before things went cray, the power couple has been spending a lot of alone time together. They have been spotted going on late-night dinner dates, afternoon trips to the park, savoring the final weeks of pregnancy.

A source tells E! News shortly before Mila reportedly gave birth:

"Ashton is not letting Mila out of sight. They are spending every moment together. He can't wait."

The source adds that Mila is so excited about the baby, but she has been very "calm and chill about it".

"She is making sure the house is prepared and the nursery is stocked.She's been very involved in everything. She really wants to be a hands-on mom."

The couple plans to raise a family together, with Mila revealing to a former interview in Marie Claire that she really wants to be there for their kids as they grow up.

"I just don't want my kids to be assholes. I feel like so many kids nowadays are. Both of us just want to have well-behaved, honest, nice children who people meet and say, 'That's a good kid.'"
