On New Year's Eve, fans were sent into a frenzy after Ashton posted a photo on Facebook, suggesting the A-list couple had tied the knot.
Wishing everyone a happy new year, Ashton shared a photo to his profile with the words "Happy New Year [love] The Kutchers" written in the sand.
Signing off 'The Kutchers', it's not surprising fans were then quick to question whether he and Mila had finally said 'I do'.
One fan asked: "Are they married??!!"
While another commented: "Wow did you guys get married? If so congrats that is awesome, you are so cute together!! Happy New Year!! Wishing you the best!!"
So far, neither Ashton or Mila have confirmed or denied the claims.
The pair got engaged last year, but known for keeping quiet when it comes to their private life, Ashton and Mila never announced they were set to wed.
Friends With Benefits star Mila even revealed she had been wearing her engagement ring for months before anyone had spotted it on her finger.
Speaking on The Ellen DeGeneres show in May last year, she said: "We were able to keep it private for two months. I think everyone assumed we were engaged for so long, that I was wearing the ring in public and nobody noticed, nobody commented on it."
Since Ashton proposed, the couple have gone on to welcome their first child together.
In September, Mila gave birth to their daughter Wyatt Isabelle Kutcher.
Soon after their daughter's birth, Ashton revealed their baby joy via his own website, posting five different baby photos and asking fans to guess which one was his and Mila's newborn.
Addressing his daughter's privacy, alongside the photos, he wrote: "Can you guess which one is ours, or does it really matter? All babies are cute."
After keeping coy on their engagement and their baby girl, something tells us it may be a while before we find out if a congrats really is in order for "Mr and Mrs Kutcher"...
