Mila Kunis and Ashton Kutcher are anxiously awaiting the impending birth of their first child together — a sweet baby girl. It should be any day now.

With the days until the birth winding down, Kutcher is reportedly keeping close tabs on his pregnant fiancée.

“Ashton is not letting Mila out of his sight. They are spending every moment together,” a source told E! News of the approaching birth. “He can’t wait.”

Before the precious baby girl’s arrival, Kunis is busy “nesting.”

“Right now she’s just getting everything ready,” said the source. “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.”

According to E!, the That 70’s Show alum is very excited about having a girl.

“She is beyond thrilled that she’s having a girl. She would have been happy with anything, but she is so excited that it’s a baby girl,” said E!‘s source.

Kunis told Marie Claire that she loves being pregnant and how her body has changed, noting the changes to her breasts.

“They’ve tripled in size. I was a 34A; now I’m a 36C. I’m so excited!” she exclaimed. “I’m telling everyone I know, ‘Go ahead, touch them!’”

The mama-to-be said the couple plan on a natural birth.

“We watched a couple of documentaries and we looked into the…midwife aspect of it and things, and spoke to my OB/GYN and realized that the hospital that I’m going to be laboring in does a midwife, you know, doula type of thing,” she told Ellen DeGeneres in May. “So I’m gonna do it as all-natural as I possibly can unless there’s an emergency or something.”

And she told Marie Claire in July that it will be an intimate birth.

“Two people are allowed in my delivery room,” Kunis said. “My doctor and my significant other. And he is staying above the action. He’ll be head to head. Not head to vag. Unless he wants to risk his life and see.”
