Bindi Irwin has opened up more about her upcoming wedding to longtime boyfriend Chandler Powell. The Aussie star dropped a bombshell when she revealed that her fiancé’s proposal is “the most terrifying moment” in her life.

On Monday, the daughter of the late Steve Irwin made an appearance on “Good Morning America” in New York City alongside her husband-to-be, mom Terri, 55, and brother Robert, 15. During their family interview, the couple talked about their engagement and upcoming nuptials.

When Bindi spoke about how her beau popped the question, she disclosed that it was actually a very terrifying moment for her. However, it was not because the proposal came as a shock to her, but because of what her younger brother did after she said yes.

“Chandler had set it all up with Rob so he'd be there taking pictures, but I had no idea,” the 21-year-old bride-to-be said. “So I'm there crying, hugging Chandler and all of a sudden Robert bursts through the bushes and I'm like a fainting goat, I just die. So it was the most beautiful and most terrifying moment of my life.”

Powell, 22, proposed to Irwin on the latter’s 21st birthday on July 24 with a stunning 2-carat ring after dating for six years. Both the professional wakeboarder and the “DWTS” Season 21 winner have yet to announce their exact wedding date, but they have already confirmed that it is happening at Australia Zoo next year.

This past weekend, Chandler expressed his excitement for their wedding. On the other hand, Bindi teased her wedding gown to her followers on Instagram by sharing a snap of its intricate sleeve. According to Daily Mail, Irwin’s wedding dress is most likely from Kleinfeld Bridal where the show “Say Yes To The Dress” takes place.

While preparations for their wedding are in full swing, Bindi’s estranged grandfather Bob, the founder of the Australia Zoo, made headlines for initially refusing to congratulate his granddaughter on her engagement and upcoming wedding. He has since clarified that he just made an “honest mistake” during his controversial interview and he has expressed his well-wishes to the couple.

Bob founded their family’s zoo more than 40 years ago, but he decided to resign and stay away from it two years after Steve’s passing in 2006. In 2015, he publicly confirmed that he was no longer on speaking terms with Terri and the rest of the family amid his concerns about the commercialization of their zoo.
