Robert Irwin recently ruffled feathers after enjoying a night out during a trip to Las Vegas.

And the Wildlife Warrior, 21, has let loose once again by enjoying a fun day out with his Dancing With The Stars co-stars.

Robert, who is set to compete on the upcoming season of the US program, shared a series of photos to Instagram from the outing.

In one image, the conservationist showed off his bulging biceps in a black T-shirt as he posed with his co-stars.

He couldn’t wipe the smile off his face as they enjoyed a drink at an outdoor venue.

Robert Irwin has let loose by enjoying a fun day out with his Dancing With The Stars co-stars in the US

It comes after Robert was spotted out and about with a mystery woman in Las Vegas.

The pair appeared completely engrossed in each other, walking closely and ignoring other members of their group.

The mystery woman turned heads in a white crop top that showed off her toned figure, teamed with high-waist mum jeans and white sneakers.

Her long blonde locks were styled in effortless waves and she carried a brown Louis Vuitton shoulder bag.

At one point, Robert placed a protective hand on her lower back as they made their way through the venue’s entrance.

Later on, the duo were seen laughing together in a dimly lit ramen bar, seated cozily in a booth with friends. Robert appeared delighted as he leaned in, clearly enjoying the company of the mystery woman.

Robert recently travelled to Las Vegas with his mum Terri and sister Bindi to host the annual Steve Irwin Gala.

But he has allegedly gotten himself in hot water with his mother after the night out during the trip.

A source close to the family informed Daily Mail Australia that his mother Terri is ‘deeply disappointed’ by her son’s late-night escapades, following the release of photos showing him out with a mysterious blonde beauty.

A source close to the family told Daily Mail Australia that Terri is ‘deeply disappointed’ in her son’s antics after photos surfaced of him with the mystery blonde bombshell.

‘Terri doesn’t care who the girl is. She just thinks the whole thing looks really bad, especially with Robert about to appear on the US version of Dancing with the Stars,’ the insider said.

Robert’s trip to Las Vegas was only meant to include the Steve Irwin Gala on May 10, but things took a turn when his sister Bindi suffered a ruptured appendix and was rushed to hospital for emergency surgery.

Both Terri and Bindi were forced to pull out of the gala at the last minute and Robert was left to his own devices and made the most of his freedom.

‘While the cat’s away, the mice will play. Robert doesn’t usually get much downtime, so he let his hair down,’ the source added.

‘But Terri was expecting him to keep things low-key, not hit the strip with a blonde on his arm.’
