Engaged?! Mila Kunis flashes diamond sparkler on ring finger

It's the month of diamond sparklers! First Katy Perry and Jess Mauboy flashed their faux-engagement rings (although Katy may have already ditched John Mayer), and now Mila Kunis has been spotted wearing some serious hand candy.

Which prompts us to ask… did Ashton Kutcher finally pop the question?!

The Friends with Benefits star was spotted shopping with her huge rock and mum in LA, amid rumours that Ashton was indeed planning to make it official.

And the couple's That '70s Show co-star Kurtswood Smith, didn't do much to dampen the rumours.

"They should be getting married!" Kurtswood told E! News. "Then we'll all go to the wedding and that could be the reunion. It'll be a reality show!"

Looks like Ashton's already kicked the wedding wheels in motion!

And until it's official... we'll have to make do with bridesmaid Mila below.
