We did not see that one coming! Things between Mila Kunis and Ashton Kutcher have been heating up for quite some time. A day before Valentine’s Day, Mila posted a really mushy picture of the two. And now, in the latest one, Mila - who has known Ashton since 'That 70's Show' days - was spotted with an oval cut diamond ring, which is definitely over 2 carat.

Does that mean that Mila, who has been dating Ashton since 2012, is now engaged? The engagement news was first reported by E! News. See pictures here.

The two actors, who have previously been very private about their relationship, have been seen posting cuddly pictures on Instagram of late. On Wednesday, 26 February, the day before the engagement ring showed up, Mila posted a photo to her Instagram account saying, "i love you @kutcher78".
