For the first time in years, real-life Hollywood couple Mila Kunis and Ashton Kutcher will appear together on television in the next all-new episode of "Two and a Half Men."

Kunis will make her debut on the popular comedy series in the upcoming episode on April 10, marking the first time that she and Kutcher appeared on a TV sitcom since they co-starred on "That '70s Show," reports The Hollywood Reporter. The two met back in 1998 on set of the Fox show and have been dating for the last two years. They are now reportedly engaged and expecting a baby, according to Us Weekly.

Kunis will play Vivian, a young, beautiful and free-spirited world traveler who shows up on Walden's doorstep. Walden will feel an instant connection with her and become convinced that she's "the one," even though he just got back with Kate and is about to propose to her, reports CBS News.

CBS has released two clips from the episode. In the first, the couple pokes fun at their off-screen romance when they begin talking about celebrities.

"I bet you only date hot actresses," says Vivian to Walden as they share Chinese takeout at the kitchen table.

"God no, I'd never date an actress. They're all crazy," he quips.

"I don't get this whole fascination with celebrities, anyway," Kunis' character continues. "Who cares who's dating whom or who's engaged to who or who has a sex tape that no one will ever, ever see?"

In the other clip, Walden asks for Vivian's number to keep in touch, but the drifter replies that she doesn't have a phone.

"Two and a Half Men" S11E19 airs on Thursday, April 10 at 9 p.m. EDT on CBS.
