Robert Irwin honors his late father!

The 21-year-old Australian conservationist attended the annual Steve Irwin Gala on Saturday (May 10) in Las Vegas, Nev.

There, he took to the red carpet while wearing a tan suit, and was accompanied by fellow environmentalists Ashlan Gorse Cousteau and Philippe Cousteau Jr. He also posed with actress Nomzamo Mbatha and influencer Christian Wilkins.

At the event, Robert revealed that his 26-year-old sister Bindi could not attend this year due getting her appendix removed.

“She’s going to be OK, but surgery — out of all the things we were ready for, that was not one of them. She’s just come out the other side of endometriosis and now the appendix goes,” he told People, explaining that his mother Terri also did not attend in order to help Bindi recover.

“Health is so important — it really is. Bindi has become an incredible advocate for women’s health, particularly, and I think it’s really important to prioritize getting help,” he added of his sister’s openness about her condition.

Meanwhile, before the gala, Robert was seen leaving the gym at the Bellagio Hotel in Las Vegas.

If you didn’t see, last month, Bindi reacted to Robert joining Dancing with the Stars season 34.
