Hemsworth party hangover: Liam and girlfriend Gabriella Brooks look downcast in Byron Bay

All partied out? Liam Hemsworth and Gabriella Brooks look downcast as they’re spotted for the first time since hosting a WILD New Year’s bash at his $6.5million Byron Bay mansion

Liam Hemsworth‘s space pirate-themed New Year’s party was the hottest ticket in town over the weekend.

But the actor, 30, and his girlfriend Gabriella Brooks, 24, looked rather deflated on Monday morning during a low-key outing in Byron Bay.

In the first pictures since the star-studded bash, the couple appeared downcast as they ran errands around the coastal town. 

All danced out? Liam Hemsworth and Gabriella Brooks didn’t raise a smile as they ran errands in Byron Bay on Monday, days after their epic New Year’s bash at his $6.5million mansion 

Their sombre expressions were a far cry from the lively atmosphere of their end-of-year party, which was attended by the likes of Liam’s brother Chris Hemsworth, his wife Elsa Pataky and The Voice host Renee Bargh.

Liam cut a casual figure in a white T-shirt and black shorts, which he teamed with a pair of slip-on sneakers.

He kept a low profile in a beige cap, and accessorised with oversized sunglasses.

Gabriella, meanwhile, looked effortlessly chic in a white jumper and cream skirt.

She teamed her outfit with a pair of thongs, and accessorised with a lilac tote and designer shades. 

The socialite later slipped off her sweater to unveil a simple white T-shirt underneath.

While Liam wasn’t pictured at the party, his girlfriend looked like a million dollars in a glitzy gold ensemble in a photo shared on social media.

She teamed her look with bold red lipstick, and went barefoot as she basked in the Byron Bay sunshine.

Chris looked fabulous in a shiny multi-coloured shirt, which he unbuttoned down to his pecks to give just a flash of his ripped torso.

In a picture shared by the Thor actor, his wife Elsa beamed in an elaborate pirate costume, which showed off her trim pins and svelte figure.

She donned a fluorescent pink wig and a pirate hat and had glitter on her face.
