Liam Hemsworth looked worn out on Monday as he arrived in Los Angeles with his girlfriend Gabriella Brooks after they spent a romantic weekend in Mexico.

The Hunger Games star, 33, rocked a laid-back look in an oversized black jumper, green pants and white sneakers.

He sported five o'clock shadow and kept a low profile in a baseball cap.

Gabriella, 26, looked effortlessly stylish in a baggy grey jumper and jeans.

The model drew attention to her natural beauty by going makeup free for the flight, and let her blonde hair hang loosely around her shoulders. 

The couple was accompanied by Liam's older brother Luke, 42, his parents Craig and Leonie, and two friends.

At one point, Liam looked emotional as he hugged his friend and said goodbye to her. 

It comes after Liam's ex-wife Miley Cyrus released her latest song Flowers, which many have interpreted as a diss-track against him.

Listeners noted the 30-year-old hitmaker called out the Aussie actor in the song, which is going head-to-head against SZA's Kill Bill on the ARIA charts.

Flowers - which was released on January 13, Liam's birthday - seemingly includes a reference to the former couple's Malibu home burning in the California wildfires, as well as various awkward red carpet moments between the pair.

Perhaps their most wince-worthy moment on the red carpet took place in February 2019 when Miley twerked in front of Liam during a joint interview, prompting him to step away from his wife while looking uncomfortable.

The couple first got engaged in May 2012, before splitting in September 2013 and later reuniting in 2016.

They eventually wed in December 2018 but their marriage lasted less than a year, and their divorce was finalised in January 2020.
