Mila Kunis baby bump due date is reportedly any day now, but it hasn't slowed Ashton Kutcher or Mila down. Kunis is still doing her daily prenatal yoga and Ashton has been driving back and forth to the hospital, reportedly.

E! News is reporting that Ashton Kutcher is getting ready for Mila's  labor by doing "dry runs to the hospital."

A source told E! News "Ashton has made a couple dry runs to the hospital to see exactly how long it will take them to get there. He's preparing for all scenarios and not leaving anything to chance. He wants everything to go smoothly!"

Kunis recently revealed that Kutcher will be with her in the delivery room.

"Two people are allowed in my delivery room. My doctor and my significant other," Kunis told Marie Claire magazine. "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. 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."

E!'s source said Mila and Ashton "nesting at home" before the birth. The insider said "Mila's in the homestretch and they are both very excited. It could happen any day now."

A source told OK! Magazine "She's so big, and the baby is moving a lot. Nothing makes her feel more comfortable and relaxed than being naked. [Ashton]  doesn't mind in the least, but is worried Mila will go stir-crazy before the baby even arrives."

Nesting doesn't mean they don't get out. The couple, who met when co-starred on "That 70s Show," aren't locking themselves away before the baby comes. According to a report from E! Online, Mila and Ashton are celebrating their last few days before becoming first-time parents.

Mila Kunis grabbed lunch with her fiancé in Venice, California on Wednesday, Sept. 17.

According to The Daily Mail, Kunis wore a boho-style black maxi dress and matching flip flops. Her hair was unstyled and she went make-up free below her aviator shades. Ashton wore a white T-shirt.
