Despite being on and off for ten years, Miley and Liam announced their split in August last year after just eight months of marriage.
Miley has now allegedly moved on with singer Cody Simpson, but it seems that Liam has found a new love interest of his own.
This week, Liam dismissed any potential doubts about his new relationship by publicly smooching Australian model Gabriella Brooks. The pair were seen soaking up the sun together on Byron Beach, and looked very content in each other's company.
Things seem pretty serious between Liam and Gabriella already, as he introduced her to his parents in December.
Until recently, Gabriella was known to be dating frontman of The 1975 Matt Healy. The couple broke up late last year after four years of romance, allegedly because Gabriella had grown tired of Matt's hard-partying tendencies.
A source at the time claimed - "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."
But with a serious new romance on the cards, who exactly is Gabriella Brooks?
Who is Gabriella Brooks?
Gabriella is 23 and lives in Sydney, although she reportedly also splits her time between London and LA.
She works primarily as a model after being scouted at the age of 14. Her Instagram - which boasts 193,000 followers - reveals that she is signed to no less than three modelling agencies - Priscillas Models, Storm Models, and Next Models. She is best known for her campaign work with big brands such as Topshop and Calvin Klein.
Still, Gabriella is not just a pretty face, and claims that her favourite part of her body is her "brain".
She studied Ancient History and Archaeology at Sydney University, and loves watching documentaries - which she affectionately refers to as "docos" - "Ancient Egypt fascinates me as does zoology and animals, so I love watching docos on those sort of subject areas."
Gabriella's love of animals is often referenced on her Instagram, where she has posted a vast array of photos featuring her dog. This might have given her something in common with Liam, who is also a known animal enthusiast.
How did Liam Hemsworth and Gabriella Brooks meet?
Whilst we don't know exactly how Gabriella and Liam met, we do know that Liam moved back to Australia after his split from Miley.
The pair's mutual love of sun and surf might have played a part in their blossoming romance, as Gabriella posted pictures of Byron Beach long before she was spotted there with Liam.
Gabriella has previously said that spending time with her friends on the beach is one of her favourite things to do, and describes herself as "an adventurer." "I love the great outdoors."
Rumours of a romantic link between Liam and Gabriella emerged in December 2019 as Liam invited Gabriella to lunch with his parents - Leonie and Craig - in New York.
Now that the rumours have been confirmed, sources have been quick to spread the good news about the loved-up couple.
One said that "Liam feels comfortable with Gabriella." "His family approves of her and really likes her, which is very important to him."
Another added that "Gabriella has been a breath of fresh air and she makes him very happy."
"Gabriella lets him be himself and doesn’t put any pressure on him."
Here's hoping that things keep going "swimmingly" for the two beach babes.
