Ashton Kutcher refuses to leave Mila Kunis' side as her due date approaches.
The star, 36, has been spending as much quality time as possible with the pregnant actress, who is expecting a baby girl, recently and can't wait to meet their first child.
"Ashton is not letting Mila out of his sight. They are spending every moment together. He can't wait," a source told E! News.
Kunis also isn't scared about going into labour, according to the insider.
"Mila is so excited about the baby," the source said. "She's not nervous at all. She's been really calm and chill about it all."
The Ukrainian-born star is currently in nesting mode at their $10.2 million home in Beverly Hills and is doing everything she can to get organised for their unborn daughter's imminent arrival.
"Right now she's just getting everything ready," the insider said.
"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.
"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."
The couple, who got engaged earlier this year and started dating in 2012, are planning to get married after their baby's birth.
