Mila Kunis & Ashton Kutcher Expecting Another Baby

They are already proud parents to a 20-month-old daughter named Wyatt Isabelle.  

The pair have kept Wyatt's life very private, but Ashton hasn't kept the love for his daughter quiet:

"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," Ashton shared with Ellen DeGeneres a while ago. "I think I really look at this as the greatest opportunity of my life."
