Chris and Liam Hemsworth celebrate mum Leonie's 60th birthday with their family

Chris and Liam Hemsworth had a laugh while celebrating a milestone!

The Hemsworth family got together to celebrate their mother Leonie's 60th birthday on Sunday, enjoying the sunshine and playing games.

Chris, 37, posted a number of videos to his Instagram account, including one of him joking around while his younger brother Liam, 30, played golf.

"Hole on one," the Thor star captioned his post.

In another video, one of Chris' sons is seeing swinging a golf club. "Nothing like father and son bonding time," he wrote, with the video seemingly showing the ball landing in his mouth. (We're fairly certain it was a trick.)

Chris later shared a series of photos in honour of his mother Leonie, who looked radiant during her milestone 60th celebration.

"Happy 60th to the greatest mum on earth 🥳🥳🥳love ya mum xo," he wrote alongside the post.

Meanwhile, Liam shared a sweet black and white pic of him and his mother. "Best mum ever. Best person ever. Love u endlessly. Happy birthday Lones ❤️❤️," he captioned the photo.

Fans were shocked to learn of Leonie's age, quickly commenting on both posts about her youthful appearance.

"Your mum is 60?!! Wow she looks great!" one user wrote.

"She looks like your sister... happy birthday to her," another commented.

Chris and Liam recently celebrated their eldest brother Luke's 40th birthday, dressing up for Luke's Peaky Blinders themed party. They were joined by their parents, Craig and Leonie, as well as their partners: Chris' wife Elsa Pataky and Liam's girlfriend Gabriella Brooks.

"Happy 40th birthday @hemsworthluke you big legend !!" Chris wrote via Instagram.
