Bindi Irwin posts prom photo with Chandler Powell

BEERWAH, Australia, April 15 (UPI) -- Bindi Irwin delighted fans by posting a throwback prom photo with Chandler Powell this week on Instagram.

The 17-year-old Australian conservationist posted a collage of pictures with the 19-year-old American wakeboarder that were taken last year at Powell's prom.

"1 year ago," Irwin captioned the post. "We don't really have prom in Australia but this wonderful human being is American and when his prom came around he invited me to Florida to go with him.

"I can't believe this really happened, I felt like I was living in a movie and was a real life Disney princess," she gushed. "Gosh I'm blessed. Thank you @chandlerpowerll it meant the world to me."

Irwin and Chandler met in 2013 and made their red carpet debut as a couple in September. The conversationist told People in September she and Chandler make their long-distance relationship work by talking every day and seeing each other every couple months.

"He's a sweet, sweet person," the star later told Women's Weekly. "He's the first person I've met who understands my life -- the travel and the work and the real dedication and determination. I think that's why I love him so much -- because he gets my world."

Irwin and Chandler were spotted kissing in Hawaii in January after reuniting over the Christmas holidays. Irwin and professional dancer Derek Hough had won Dancing with the Stars Season 21 just months before.
