Jewish-Ukrainian actress Mila Kunis is engaged to long-term boyfriend and kabbalah enthusiast Ashton Kutcher.

The Black Swan star, 30, was seen wearing a large diamond ring on her wedding finger while shopping with her mother Elvira in Los Angeles this week, prompting unconfirmed reports of an engagement in E! Online and People magazine.

Ms Kunis and the non-Jewish American actor, 36, met while playing an on-off couple on the popular American sitcom, That 70s Show.

They have been in a relationship for the past two years and were often seen shopping together around Belsize Park, north west London, as she filmed Jupiter last year.

Last year, Mr Kutcher was seen comforting the actress at the funeral of Kaballist Rabbi Philip Berg in Safed, Israel.

Ms Kunis, who moved to the US aged seven, has reportedly spoken about her intention to have “Jewish babies” with the Two and a Half Men actor.
