The 29-year-old Black Swan star and her actor beau were snapped in Los Angeles on Saturday looking more like two and a half celebs!
Yep, that definitely looks like a bump to us.
The usually-tiny Mila has kept a low profile since she started dating Ashton, who sensationally split from wife Demi Moore last November.
Mila let slip that she was feeling clucky in an interview with Glamour magazine earlier this year.
"I do want a family," she confessed. "I’d rather be in love and have a baby than a movie."
Ashton and Mila have been snapped together nearly every day since going public with their relationship last month. The pair have been friends for years since starring together on That 70s Show in the late 90s.
