Mila Kunis and Ashton Kutcher "tag team" work for the sake of their children.
The Black Swan actress - who has Wyatt, 11, and Dimitri, eight, with the 47-year-old actor - knows it is a "luxury" that she only needs to work on one project a year but she and her husband feel "fortunate" to be able to arrange their careers around the needs of their family.
