Mila Kunis As Vivian
She played Vivian, a free-spirited hiker, and real-life love interest of husband, Ashton Kutcher. Walden was about to propose to his girlfriend of Season 10 when she got back from vacation, but he met Vivian instead. What more could you ask for with a Mila Kunis cameo? She isn’t seen after this episode, but don’t you love seeing Jackie and Kelso onscreen together? (There’s even a That 70’s Show nod in the episode)
