If this pregnancy is still just a rumor, then it's reaching pretty far. Mila Kunis and Ashton Kutcher have confirmed their engagement, but they're keeping tight-lipped about the pregnancy that everyone can't stop talking about. Their expected due date is some time in September and now US Weekly is reporting that Mila Kunis is having a girl, according to multiple sources. These sources, of course, still have yet to actually include Kunis or Kutcher.
This will be the first child for him and for Kunis, but his last high-profile relationship was with Demi Moore, who has three girls of her own. Kutcher never legally adopted Rumer, Scout, or Tallulah Willis, but in the eight years that he was with Moore he acted in loco parentis. "He’s like a friend as well as a stepdad. We talk about everything, auditions, boyfriends, family," Rumer Willis said about Kutcher back in 2009. "He understands more than my parents sometimes because he’s closer to my age."
As one source notes in the US Weekly article, Kutcher "got plenty of practice with Demi's girls", which means he's better equipped than most new fathers are to deal with the trials and tribulations of the female experience. The three Willis daughters were relatively close in age, but eight years seems like more than enough time to hit most of the high and low points that come with being a teenage girl. At least, the high and low points he didn't already gain experience in via dealing with his older sister, Tausha.
If nothing else, Kutcher has a world of experience in raising a child in and out of the public eye, a skill which many celebrities never truly master. And considering that Kunis gave an interview to Playboy in 2013 where she expressed her desire to be a "present mom", he'll have plenty of help.
