Not only are Mila Kunis and Ashton Kutcher living the dream off screen but the newly pregnant couple is taking their chemistry onscreen.

Unfortunately they will not be reprising their roles as Jackie and Kelso from Fox's "That '70s Show" instead the engaged pair are taking their comedic chemistry to CBS.

According to Us Weekly, the gorgeous brunette will appear on her boyfriend turned fiancé turned baby father's show, "Two and a Half Men." Along with this news comes the first pictures of the couple working together since their time on the period comedy.

Kunis, 30, filmed the episode prior to the pregnancy news and will portray the role of Vivian, "a young, beautiful, free-spirited world traveler who shows up on Walden's doorstep," a press release about the casting news stated. In the episode Kutcher's character Walden will develop feelings for her.

The press release stated, "Walden feels an instant connection with her, convinced she's 'the one.' The problem is, Walden was about to propose to someone else."

Although it will be interesting to see how Walden handles his conflicted heart, fans are most likely more interested in the actor's personal life.

Since Ashton Kutcher and Mila Kunis began dating in 2011 the pair has been inseparable and they are now engaged and expecting their first child together.

As baby news broke a source revealed, "This is something they both wanted," adding, "They are both so happy."

"Two and a Half Men" airs Thursdays at 9:30 p.m. on CBS.
