The Irwin family also dished on the upcoming Steve Irwin Gala -- and the special gift Ed Sheeran donated to the cause.
Chandler Powell loves Bindi Irwin!
ET's Lauren Zima sat down with Powell and the Irwin family in Los Angeles on Wednesday, where he opened up about how life has changed since he started dating Bindi Irwin -- and revealed that he couldn't be happier.
"I am the luckiest guy in the world," he gushed. "It's amazing to be part of such an incredible cause and to work for Steve's legacy and to do alongside the most beautiful girl in the world."
"And to have the best teachers alongside me, it's incredible. It's such fulfilling work. I love it," he added.
The 21-year-old left his professional wakeboarding career in Florida to help Bindi and her family with their conservation work in Australia and hasn't looked back since. "Being in lakes, we had turtles and alligators and snakes, and I love wildlife and conserving it and teaching people about it," he explained. "Now to do it full-time is incredible."
Powell isn't the only Wildlife Warrior the Irwin family has recruited -- Ed Sheeran donated a guitar to the Steve Irwin Gala after hanging out with the Irwins at the Australia Zoo.
"He was feeding crocodiles and holding snakes and then he said, 'How can I help?' and he ended up donating a signed guitar to our gala dinner," Bindi shared. "So we can auction it off and raise lots of much-needed funds for Wildlife Warriors... It's just extraordinary how many people have come together from all over the world to make a difference and remember Dad and everything that he stood for so it is. It's a true blessing, honestly."
For Bindi's brother, 14-year-old Robert, the gala is a time to celebrate Steve, after his tragic death in 2006.
"It's great to get his message out, because he always said, 'I don't care if people remember me, I want them to remember my message,'" he said. "So to continue that and have that in the forefront of peoples mind, it's really what he would have wanted."
"It's really great to celebrate everything that he loved and to get everyone really passionate about the cause," he added.
The Steve Irwin Gala takes place May 5 in Los Angeles. See more on the family in the video below.
