Chris Hemsworth shows off his muscles as he takes off his wetsuit while surfing with brothers

Chris Hemsworth showed off his famous Thor physique as he stripped off his wetsuit during a surfing session with his brothers in Byron Bay on Thursday to celebrate his 39th birthday.

The Hollywood hunk tucked his board between his thighs and tucked the top half of the suit down around his hips for more comfort before heading down the beach.

Chris hit the waves on his big day doing what he loves most – surfing with his equally handsome brothers Luke and Liam Hemsworth.

Chris showed off a few tricks on his white and maroon board and later became friends with his eldest brother Luke, 41, as they walked along the beach.

Meanwhile, Liam, the youngest at 32, was spotted casually sliding through a much bigger wave.

The Hunger Games star waded back onto shore with a big smile on his face and a laugh with one of the friends the trio had brought along.

However, it appeared that his wetsuit became uncomfortable when he adjusted a little later during the outing.

While Luke joined in the fun, he seemed content to wade his board in the shallows and walk along the beach with Chris as they wrapped up the day.

It comes after Chris’ wife Elsa Pataky celebrated his birthday by posting what appeared to be a nude photo of the star in the bath with a parrot on her head.

The Spanish model and actress, 46, shared the snap on Instagram to mark her husband’s birthday.

“Happy Birthday to my favorite parrot trainer, nanny and animal trainer,” she captioned the post.

She continued, “There’s nothing you can’t do. We love you to the moon and back,” before writing more in Spanish.

Elsa uploaded the photo alongside two others, including one of the Thor stars wrestling with their three children: daughter India, nine, and twins Sasha and Tristan, both eight.

The third image was a black and white still from Thor: Love and Thunder, which featured Elsa as the “Wolf Woman” who was a former lover of Chris’ character.

The lovebirds began dating in early 2010 and tied the knot in a low-key ceremony in December of that year.

They now reside with their children in a $30 million mansion in Broken Head, near the celebrity enclave of Byron Bay.
