Mila Kunis and Ashton Kutcher are reportedly engaged.

E! Online has obtained snaps of the Black Swan actress shopping yesterday (February 27) and sporting a huge diamond sparkler on her wedding ring finger.

The website adds that a source has since informed them that Kunis and the Two And A Half Men star are indeed planning to tie the knot and make their relationship official!

Kunis and Ashton have been dating since April 2012, following Kutcher's public split and eventual divorce from wife Demi Moore.

They first met on the set of sitcom That '70s Show, where they played the roles of Kelso and Jackie between 1998 and 2006.

Earlier this month, both Ashton and Mila posted the same smiley snap of themselves on Instagram, with the account attributed to Kunis accompanying her pic with the caption: ""I love you @kutcher78."

There is still no official word from the couple, but keep it MTV News UK for more…
