Mila Kunis has a new acting gig -- this time, starring opposite her new fiance, Ashton Kutcher, in a guest role on Two and a Half Men! 

According to The Hollywood Reporter, this will be the first time that the duo has reunited on-screen since they starred together on That '70s Show. Kunis will play Vivian, a world-traveling, free-spirited girl who shows up on Walden's doorstep (Walden, of course, is played by Kutcher). Walden feels "an instant connection" to her (not exactly a stretch here), and feels that she's "The One." The problem, of couse, is that Walden is about to propose to someone else. (Well, we hope THAT part isn't based on a true story!)

And, according to the New York Daily News, CBS made the announcement of Mila's guest appearance yesterday. No word yet on when Mila's episode will air, though we're sure it's going to be a ratings winner!

In 1991, at the age of seven, Mila moved from the Soviet Union to Los Angeles with her family. After being enrolled in acting classes as an after-school activity, she was soon discovered by an agent. She appeared in several television series and commercials, before acquiring her first significant role prior to her 15th birthday, playing Jackie Burkhart on the television series That '70s Show. In September 1999, she began voicing Meg Griffin on the animated series Family Guy. Her breakout film role came in 2008, playing Rachel Jansen in Forgetting Sarah Marshall. Subsequent film roles included Mona Sax in Max Payne, Solara in The Book of Eli, Jamie in Friends with Benefits, Lori in the comedy Ted, and Theodora in Oz the Great and Powerful. 

Although Kunis has described herself as a "computer nerd", she does not have a Myspace, Facebook or Twitter account. Kunis discussed her desire for privacy: "Why would I want to share my life with the world when it's being shared already, without my consent? The only problem with not having an account is that there are fake accounts, pretending to quote me. But what am I going to tweet about?"
