Mila Kunis is showing her devotion to rumored fiancé Ashton Kutcher by making a guest appearance on his hit series.

The Wrap” reports that Kunis will join her fellow “That ‘70s Show” alum for an episode of “Two and a Half Men” on CBS.

Her character, Vivian, is described as “a young, beautiful, free-spirited world traveler who shows up on Walden’s (Kutcher) doorstep.”

Kutcher joined the sitcom in 2011, replacing the outgoing Charlie Sheen after a volatile behind-the-scenes battle.

Kunis and her alleged fiancé first met starring opposite one another as friends and sometime romantic partners on FOX’s “That ‘70s Show,” which ran for eight seasons.

She stayed on for the show’s entire run, while Kutcher, who played Michael Kelso, dropped down to a recurring role for the show’s final season.

The couple is believed to have gotten engaged late last month. It would mark the first marriage for Kunis, while he was previously married to Demi Moore.

Will you tune in for Mila and Ashton’s on-camera reunion?
