The Hollywood stars finally tied the knot in an intimate Stateside ceremony over the 4 July weekend, with a source confirming the happy news to US site People. Yay!
Although no formal details of the wedding have been released yet, we're sure it would have been a dreamy occasion. Mila regularly tops our best-dressed lists with her chic red carpet gowns so we can only imagine she donned a stunning dress.
And we're imagining that she twisted her hair into a beautifully boho style too and framed her eyes with her trademark smoky tones. Oh what we'd do to see some pictures...
We're really hoping the duo are actually man and wife for real this time as we got all excited last December when Mila was snapped with a band on her ring finger at a basketball game.
And in March this year, the Black Swan beauty set the rumour mill into action again by giving James Corden a coy response of 'maybe' when he asked if they were already hitched.
We're so pleased to see that Mila, 31, and Aston have gone the distance - they met way back when while playing love interests on sitcom That 70s Show as youngsters.
They confirmed their adult relationship in September 2012 when they were seen enjoying a PDA in New York's Central Park, and the birth of a little girl named Wyatt only strengthened their bond 9 months ago.
'The most amazing thing about having a baby is my partner, Mila,' Ashton, 37, gushed during a TV interview shortly after their daughter's arrival.
'She’s the greatest mom, I can’t even. I go to work every day and I come home and she’s like perfect. It just seems like everything went amazing. And I know that something probably didn’t go amazing, but she never tells. It’s unbelievable. She’s incredible.'
