Robert Irwin sends fans wild as he shows off his muscular arms while rescuing turtle off highway

Robert Irwin has sent his fans wild with his latest post.

The Wildlife Warrior, 21, took to Instagram to share a rescue of a freshwater turtle that was stuck on a highway.

In the video, the TV presenter is seen carrying a turtle off the bitumen to the side of the road. 

Wearing a green mesh knit shirt with short sleeves, his biceps and muscular forearms were on prominent display. 

'I've just pulled over, because this bloke's right in the middle of the road,' he said.

'I saw a couple of cars go pretty much right over him but I don't think he's been hit...he looks fine externally but it's dark I can't quite tell so we're going to take him to our wildlife hospital.'

Robert was then seen dropping the turtle off at the hospital, before getting the all-clear and releasing the animal back to a body of water.

Fans took to Robert's comments and left thirsty remarks about the young hunk's good looks and physique.

'Can you please cut back on the gym hours a little, Robert? The pecs and biceps getting too big!' said one follower.

'Lucky turtle,' wrote another follower, while a third said 'I would absolutely marry Robert like yesterday. So dreamy.'

'That shirt looks good on you,' wrote someone else.

Another thirsty commenter wrote, 'We need to see that chest!' 

It comes as Robert allegedly got into hot water with his mother Terri over his rugged new magazine photoshoot. 

The TV presenter debuted a very handsome new look as he ditched his signature Australia Zoo khakis while posing for Stellar Magazine over the weekend.

He showed off his modelling credentials in the dapper new cover shoot, which saw him sport an array of suave outfits as he put his best fashion foot forward.

In the magazine spread with the apt title 'a grown-up conversation with Robert', the conservationist showed off his muscular frame in a white vest top and washed-out jeans.

He also sported an edgy leather jacket as well as a suave Calvin Klein denim ensemble as he took a career step into modelling.

Though he sent tongues wagging with the shoot, his momager Terri, 60, was said to have been less than impressed by what she deemed to be 'thirst trap' photographs.

A source exclusively told Daily Mail Australia that Robert has 'upset' Terri with the magazine cover shoot, which came out on the same day as his 21st birthday on Sunday.

'Terri Irwin has been quick to point out that the recent photoshoot has come off as a 'thirst trap' for her son and that hasn't sat well with her,' the source claimed.

'The famous momager usually is across everything that her children Bindi and Robert put out into the media but somehow a series of photos got over the line, breaking one of her golden rules on not "sexualising" the Irwin brand.

'Everything is connected back to the Australia Zoo and family friendly branding, even the team behind the I’m A Celebrity machine know that Terri doesn’t want Robert positioned as a "sex symbol".

'I think Terri felt blindsided by these pictures and the new attention Robert has been getting by new fans,' they added.

The source also claimed that the photoshoot has carved out newly-single Robert's place as 'Australia's most eligible bachelor'. 

'The comments section from "thirsty Mums" in their thirties has been the most entertaining to read. No wonder Terri is anxious,' they said.
