Washington  - Mila Kunis and Ashton have sparked rumours they’ve gotten married. The ‘Black Swan’ actress, who gave birth to a baby girl, Wyatt Isabelle, with the 36-year old actor in late October, has fuelled speculation she may have recently tied the knot with her former ‘That 70s Show’ co-star after being spotted wearing a new platinum band below her diamond engagement ring while enjoying a rare date night with him on Friday, December 19, 2014. The 31-year old beauty made no attempt to conceal the ring as she and her fiancé watched the Los Angeles Lakers take on Oklahoma City Thunder at the Staples Centre.
