Actor Ashton Kutcher is reportedly engaged to his girlfriend Mila Kunis.
The Black Swan actress was spotted wearing a sparkling diamond on her left ring finger while out shopping in Los Angeles on Thursday and a source tells E! News that the couple is in fact planning to tie the knot.
Kutcher and Kunis met in 1998 as co-stars of the popular U.S. sitcom That '70s Show, in which they played an on-screen couple.
However, their off-screen romance did not begin until April, 2012, months after his 2011 separation from ex-wife Demi Moore after six years of marriage.
Kutcher and Moore's divorce was finalised last November. Copyright WENN.com
