Mila Kunis and Ashton Kutcher are engaged and expecting their first child together–there is no denying the real love and chemistry these two share off screen. But the lovebirds and former That ’70s Show costars have just announced that they will also bring their comedic chemistry to TV once again, in an upcoming episode of Kutcher’s CBS show Two and a Half Men.

Kunis is set t o play “a young, beautiful, free-spirited world traveler who shows up on Walden’s doorstep.” And of course, “Walden feels an instant connection with her, convinced she’s ‘the one’…The problem is, Walden was about to propose to someone else.”

Seems like TV is somewhat mirroring the couple’s real life love for each other. A source says of the two, “They are happy, healthy and excited to start a family.” The source adds, “There is no rush to get married. The wedding  will be very intimate and private.” Kunis “is all about being a mother.”
