Chris Hemsworth trolls Liam Hemsworth on his birthday by telling him to 'get in shape'

• Chris Hemsworth shared a post on Instagram in honor of Liam Hemsworth's 32nd birthday.
• "Hopefully this is the year you finally get in shape and take care of yourself," Chris jokingly told Liam.

Chris Hemsworth trolled his younger brother Liam Hemsworth on the actor's 32nd birthday.

"Happy birthday @liamhemsworth hopefully this is the year you finally get in shape and take care of yourself To help with your transformation I'm gonna gift you 10% off a @centrfit membership #familydiscount love you," Chris captioned a post shared on Instagram on Thursday, referencing his fitness site and app called Centr that features workouts, healthy recipes, and meditations.

Chris posted three images of his sibling, beginning with a shirtless photo showing Liam's ripped chest and arms. The second photo showed Liam giving the camera a thumbs-up while surrounded by balloons, flowers, a birthday cake, and gifts. The last image in the post gave fans a glimpse of young Liam.

This isn't the first time Chris has poked fun at a costar or family member.

In honor of Liam's 31st birthday in 2021, the "Avengers: Endgame" star posted a throwback photo of the duo taken during their childhood and wrote: "Happy birthday @liamhemsworth this photo was taken 3 years ago today, damn time flies but you haven't changed a bit."

Liam and his older brother, Luke Hemsworth, got revenge on the Marvel star later that year on his 38th birthday, by posting separate photos online that didn't actually include Chris.
