According to a new report, Shia LaBeouf is engaged to on-and-off girlfriend Mia Goth!

After the actor, 29, referred to the model as his fiancée during a performance art project last month, he allegedly told a cashier at the grocery store Gelson's that the duo is set to be married. An onlooker tells Us Weekly that Mia was wearing a large diamond ring on her left hand.

The pair began dating after meeting on the set of Nymphomaniac: Vol. II in 2012, and sparked engagement rumors as early as last March when the Brit stepped out sporting bling on her ring finger.

But as Life & Style previously reported, the couple appeared to take a break in July after they were caught on video engaging in a pretty intense fight.

Looks like they've found a way to make it work!
