Engaged Mila Kunis will be dropping in on fiance Ashton Kutcher's hit sitcom "Two and a Half Men," CBS has announced Tuesday just days after the pair's reported engagement.

It would be a long-delayed reunion as engaged couple Mila Kunis and Ashton Kutcher last worked together as lovers was on "That '70s show," which ran for eight seasons until April 2012.

According to CBS, the "Jupiter Ascending" star will play the character of Vivian, described to be a "young, beautiful and free-spirited" wanderlust who drops in on the doorstep of Ashton Kutcher's character, Walden. The two immediately felt a romantic connection.

Just like in real life, Ashton Kutcher's character will believe that Vivian will be "the one." Of course, there's going to be a major obstacle since Walden is about to propose to somebody else, E! News eported.

The network, however, did not issue a release date for when the episode with the recently engaged Mila Kunis will air. There's also no word how many episodes will include the petite actress or whether she will become part of the regular cast or not.

Another insider told Us: "He wants to marry her soon and start their life together. He was planning this all along."
