The pair, who have been together for three years, were first spotted together in December 2019 at a brunch with the actor's parents, Craig and Leonie, in Byron Bay, New South Wales, Australia.

"Liam and Gabriella have spent a lot of time in Australia together," a source told PEOPLE of the duo in January 2020, adding at the time that they were "getting serious."

The couple went Instagram official in June 2021, with Liam sharing a photo of himself, Brooks and his brother Chris Hemsworth along with Chris's wife Elsa Pataky and Matt Damon's wife, Luciana Barroso, in attendance at the Gold Dinner 2021 in Sydney.
