Liam Hemsworth spotted introducing model Gabriella Brooks to his parents

Liam Hemsworth has sparked speculation that he's dating Sydney model Gabriella Brooks following his separation from Miley Cyrus.

The 29-year-old was photographed by the Daily Mail introducing Brooks, 21, to his parents Craig and Leonie on December 16 in Byron Bay.

The photos show Hemsworth smiling and hugging members of the family, before they all sit down for a casual lunch.

Brooks, who is based in Sydney's Northern Beaches, shared a snap of the Byron Bay beach to Instagram on December 1, and captioned it with a heart emoji.

Meanwhile, Hemsworth jetted down to the beachside town after wrapping up filming Dodge and Miles in Canada.

Brooks, who used to date 1975 lead singer Matt Healy, split from him after a four-year romance.

There was a "strain on their relationship, not helped by him being on tour a lot this year," a source told The Sun on August 29.

"He parties a lot at home when he's there and Gabby had just had enough. She doesn't want to lead her life like that."

Hemsworth was previously rumoured to be dating actress Maddison Brown after they were spotted kissing in New York on October 12. It's unclear whether they are still seeing each other.

He announced his split from Miley Cyrus in August, only eight months after they got married and 10 years of on-again, off-again dating.

Meanwhile, Cyrus has since enjoyed a whirlwind romance with Kaitlynn Carter and is now dating Cody Simpson.
