Chris Hemsworth Trolls Brother Liam For His Birthday

Chris Hemsworth is once again trolling his younger brother Liam Hemsworth -- this time, offering a family discount to his health & fitness company, Centr, in honor of his 32nd birthday today (January 13).

The Thor star took to Instagram to hilariously poke fun of his brother on his special day. Alongside three photos of the Hunger Games actor, Chris, 38, wrote, "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."

In the comments section, one fan commented, "Family discount on a membership is the best present you can give your brother 😂," while another wrote, "I mean, product placement in happy birthday wish 😂"

Liam later responded to Chris' generous "gift" in an Instagram video, which was coincidentally filmed at a gym. "Special thank you to my brother Chris for giving me 10 percent off on a Centrfit membership," Liam said with a big grin. "I mean, what a gift! The gift of health. Really appreciate it, mate. That's just the kick in the a-- that I needed to continue on my fitness journey. Here's to a happy, healthy year, everyone. Lots of love."

Chris loves trolling his younger sibling, giving him the fan treatment last month in a series of black-and-white photos of the two, bearing a striking resemblance to one another. The bearded Aussies were dressed in white t-shirts and clasping hands, while Chris captioned the post, “Always great interacting with my fans. Met this young lad recently, reminded me of my younger self. Not in looks, but just a real go getter attitude. He insisted on the resemblance and I assured him no one else has this look. Was great to meet you Leon good luck in the future.”

Happy birthday, Liam!
