The Hunger Games alum, who has been dating Gabriella, a Sydney-based model, since 2019, popped up in an Instagram post from Michele Merkin, a close pal of Gabriella's. A slideshow dedicated to her best friend features a picture of Gabriella and her friends, with Liam posing high in the background. Michelle captioned the post, "Wishing you giggles for life! #hbd #gg." Liam and Gabriella were first spotted together in Australia's Byron Bay in December 2019, where Aussie Liam and his brother Chris have settled when not working on projects. One of their first public outings included them having lunch with his parents, Craig Hemsworth and Leonie Hemsworth, which made fans assume that the two were getting serious. At the time, Liam had recently split from his ex-wife Miley Cyrus. Both Gabriella and Liam have kept their romance fairly private. She was even spotted celebrating his brother Luke's roaring '20s-themed birthday last November.
