Congratulations to Mila Kunis and Ashton Kutcher; according to E! News, the celebrity couple are expecting their second child.

Their new arrival will make Wyatt, their firstborn, a proud big sister as the Kutcher/Kunis brood grows.

Wyatt, whose full name is Wyatt Isabelle, is just twenty months old so it looks like this pair will have their hands full for quite some time. It's been non-stop since they married last July.

Kutcher and Kunis famously met on the set of That 70s Show where they played fictional boyfriend and girlfriend. After a string of respective relationships, they eventually wound up back together and today, they're nuts about each other. Kutcher made his fans weak when, on Ellen, he described how it feels to come home to Mila and Wyatt after a day's work:

"[Mila]'s the greatest mom... I go to work every day, and I come home and she's perfect. And it just seems like everything went amazing. And I know that something probably didn't go amazing, but she never tells … It's unbelievable. She's incredible... "You think you know how much you can love another person, and then you have a child and you realize you didn't know. It's infinitely rewarding... I think I really look at this as the greatest opportunity of my life."

Meanwhile, a source close to Kutcher tells People: “Ashton genuinely lights up when talking about Wyatt and the little one on the way... Everything about being a father is natural to him.”

Aaaaaand there goes our ovaries.
