Liam Hemsworth is going Instagram official with his model girlfriend, Gabriella Brooks.
The couple attended the Gold Dinner 2021 charity gala in Sydney alongside Hemsworth's brother Chris, Chris' wife, Elsa Pataky, and Matt Damon's wife, Luciana Barroso.
Liam Hemsworth, 31, shared two Instagram pics of himself and Brooks dressed in formalwear at the gala, which was hosted by the Sydney Children's Hospitals Foundation and helped raise funds for children and adolescents with mental health issues.
Hemsworth opted for a black suit with black shirt and tie, while Brooks, 23, looked stunning in a black Dior sleeveless gown with plunging neckline.
Hemsworth's first pic shows the couple posing with their arms around one another as they stand next to Hemsworth's brother, his wife and Barroso. A second candid shot finds the whole gang hamming it up for the camera while seated at their dinner table.
"Fantastic night raising much needed funds and awareness for one of the most important and challenging issues, children’s mental health," the actor wrote in his caption.
Though it's the first time Hemsworth or Brooks have shared an Instagram pic with one another, they previously appeared together on Chris Hemsworth's Instagram page in a pic Chris posted in November 2020 to wish brother Luke Hemsworth a happy 40th birthday.
The couple can be seen posing alongside Luke and his wife, Samantha, Chris and Elsa, and the Hemsworth family's parents, Craig and Leonie.
Liam Hemsworth, who was previously married to pop star Miley Cyrus, told People magazine in May 2020 that he and Brooks had been quarantining together in his native Phillip Island, Australia, revealing that the couple passed the time playing Scrabble.
"I used to play with my grandma when I was a kid. She loved Scrabble," Hemsworth recalled. "It made me nostalgic and brought back memories."
The couple were first spotted together in December 2019 while eating lunch with Hemsworth's parents in Byron Bay, New South Wales, Australia, People reported.
