Ashton Kutcher and Mila Kunis are reportedly engaged. US Weekly and E! News have both announced the happy event, but it all remains unofficial.

The news that the young Hollywood couple are set to marry came after Kunis was spotted wearing a sparkler on her left hand while shopping with her mom at The Grove in LA on Thursday, February 27. The ring looked clearly like a large diamond in a platinum setting, which immediately sparked rumors of an engagement.

Next came the reports of an Instragam post from a certain kunismilena, which showed a photo of the lovebirds and a caption that said, "I love you @kutcher78." However, the accounts mentioned have both been proven to be fake.

Despite multiple anonymous sources confirming the engagement, Kunis and Kutcher themselves haven't made it official. The Two and a Half Men actor, who is very active on Twitter, hasn't posted anything about it yet.

Kunis and Kutcher were once a reel life couple - Jackie and Kelso - on the Fox sitcom, That '70s Show. They were co-stars for years without any romantic involvement, but were certainly good friends.

Kunis was in a relationship with actor Macaulay Culkin for eight years, while Kutcher was married to actress Demi Moore for five years since 2005. Both of them became single in 2010, and finally became a real life couple when they started dating in early 2012. Both were coy at the very start, denying relationship rumors until they owned up to being with each other a few months in. They have kept their relationship very private since.

When Kutcher and Moore's divorce was finalized in 2013, talks of an engagement were already in the news. Sources confirm how crazy they were about each other and their desire to take their relationship to the next level and get married. However, the couple has certainly taken their time - until now, after almost two years.
