Even Bindi Irwin has to curse every now and then.

The daughter of late conservationist Steve Irwin is known for her positive, squeaky-clean image, but on Monday’s episode of Dancing with the Stars, the 17-year-old was bleeped in a pre-taped package that showed the moment after she fell to the ground during a rehearsal.

“Oh my gosh,” Irwin told PEOPLE after the show. “I felt so bad. But I just wasn’t expecting it. I was dropped and so I just screamed and it came out. I couldn’t even tell you what word I said.”

And her pro dancer partner Derek Hough couldn’t say either.

“I wouldn’t be surprised if all she said was ‘poop’ or something,” said Hough, 30.

But Irwin admits it’s not the first time she’s cursed.

“A few years ago, my family was staying in a really old house in the Outback and the power was out so we just had candlelight. I came in and put my bag down and a mouse jumped from the bed over my shoulder,” said Irwin. “I wasn’t expecting it. I thought it was a ghost or something so I screamed and I swore. From that day on, my mom and brother have called it ‘the mouse word.’ ”

And Irwin has a feeling she’ll be hearing that term in the next few days after her outburst on the ABC reality dance competition.

“I’m going to be getting a lot of, ‘Bindi Sue! You said the mouse word,’ ” she said.
