Ashton Kutcher has recruited his real-life fiance Mila Kunis for an upcoming guest spot.

Mila will play Vivian, a free-spirited traveler who has a love-at-first-sight encounter with

Walden. The trouble is, of course, that Walden is about to propose to someone else. This

will mark the first small-screen reunion for Ashton and Mila since they co-starred together

on That 70s Show for eight seasons. Look out for her guest spot later this Spring, and

be sure to stick with us at Celebified for more of the latest TV scoop.
