Rumored to have been dating since April, the couple were spotted holding hands earlier this month boarding a plane when they vacationed in Bali and now the hot duo had date night with Mila's parents.
The four of them were seen attending a Los Angeles Dodger Game Thursday night. Eonline.com reports they sat in the Lexus Dugout Club together and chowed down on snacks as they cheered for the team, which you can see in the video below.
Mila, 28, and Ashton, 34 have been friends for well over a decade and costarred together on That 70's Show. She was in a long term relationship with Macaulay Culkin at the time and went on to marry Demi Moore, whom he recently divorced.
Up until recently Mila denied their relationship and told British Elle's August issue she was "totally single" and claimed her and Ashton are "just friends."
"Listen, [Ashton and I] hang out. We've known each other for 15 years. We have mutual friends. We're comfortable with one another. That's it! There's no crazy love story, nothing more."
