Ashton Kutcher and Mila Kunis are engaged!

It was only a matter of time before this perfect couple made it official…

Apparently Ashton Kutcher has finally put a ring on it and asked Mila Kunis to marry him. #WOOP

Mila was papped earlier today with a huge rock on her ring finger – which obviously caused the rumour mill to almost combust with ideas of a That 70s Show reunion wedding.

And a source close to the pair seems to have confirmed what everyone was hoping - telling E! News that they are defs engaged.

Ashton and Mila have been dating for almost two years after hooking up in April 2012.

Originally they were both reluctant to go public with their romance. But being two A-List superstars they could only keep things on the down low for so long, and were soon stepping out in public together looking well and truly loved up.

The seriously hot couple still refrain from talking about their relationship to the press, but Mila made a big fat show of affection on what is believed to be her Instagram account yesterday, posting this adorable selfie with the caption “I love you @Kutcher78.”
