Mila Kunis & Ashton Kutcher engagement 'surprise' after 'That 70s Show' feud? Demi Moore divorce 'reunites' lovers, baby bump soon?

Did fans know that Mila Kunis and Ashton Kutcher were never really that close on the set of "That 70s Show?" Now, they're getting married!

A source reveals to RadarOnline, "Everyone shakes their head over the romance... Ashton and Mila were absolutely not friends during much of the making of That '70s Show. In fact, they couldn't stand working together."

Kunis' "spoiled rich girl" character (Jackie Burkhart) played Kutcher's on-and-off again love interest (fans remember goof-ball, Michael Kelso) on the show. But according to the couple's mutual friend, "The two were never close on the set. Quite the opposite!"

Apparently, the two despised each other back then! But now, 30-year-old Kunis and 36-year-old Kutcher can't get enough enough of one another's love.

And the thing that brought them back together? Kutcher's divorce from ex-wife, Demi Moore. "Mila was the one who came forward to bury the hatchet," the source explains. "She could see Ashton was going through a tough time and reached out to him. They built a solid friendship, which was a new thing for both of them."

Back in 2011, rumors suggested that the sexy actor cheating on Moore with a young woman. They officially divorced in November 2013. Kutcher began dating the former "Sexiest Woman Alive" in April 2012.

That growing friendship quickly turned into love, and following his divorce, Kutcher proposed to Kunis with a massive diamond ring. Now, rumors suggest they might even try having kids soon!

The source concludes, "Everyone's amazed at how different Ashton and Mila are together from when they were younger. It's such a total change and now they're a match made in heaven - something that no one could have ever predicted in their wildest dreams back then!"

Do fans think they make a cute couple?
