Ashton Kutcher and Mila Kunis, who got engaged in February last year and welcomed their daughter Wyatt eight months later, have fuelled speculation they've recently tied the knot after the 36-year-old actor posted a cryptic message on his Facebook account on Thursday.

The hunk shared a photograph with his fans of the words "Happy New Year, (love) The Kutchers" scribbled into sand, which caused fans to jump to the conclusion that the duo have got hitched.

 

Mila, 31, was also spotted wearing a new platinum band below her diamond engagement ring while enjoying a rare date night with him just before Christmas last month.

The brunette beauty made no attempt to conceal the ring as she and her fiancé watched the Los Angeles Lakers take on Oklahoma City Thunder at the Staples Centre.

However, if the pair have got married, the news wouldn't come as a surprise to fans as Mila admitted last year that their wedding would be simple and private.

She said in August: "Now my theory on weddings is: Don't invite anyone. Do it privately and secretly. My parents are okay with that. They're just excited that I said yes. I never wanted to get married. From the age of 12, I prepared my parents for no marriage. Then things changed - I found the love of my life."

Meanwhile, Ashton was previously married to actress Demi Moore, 52, for eight years, who he split from in November 2011 after he was accused of cheating on her.
