Crikey! This is exciting news. Bindi Irwin, daughter of the late Steve Irwin, is the first celebrity announced to compete in Season 21 of ABC's “Dancing With the Stars.”

“And the first celebrity on the new season of @Dancing ABC … Bindi Irwin! #GMADancing,” “Good Morning America” revealed via Twitter Monday.

The 17-year-old animal rights activist confirmed on the morning show that she’d be trading in her safari hat for dance shoes when “DWTS” returns on Monday, Sept. 14.

“This is completely different to anything I’ve ever done in my life,” the Australian said. “I’m used to wrangling crocodiles!”

Now, instead of going toe-to-toe with toothy beasts, the daughter of the late “Crocodile Hunter” will face cha-cha-ing competitors during the upcoming season of the dancing series. Irwin dished that she’s a bit nervous to perform in front of the judges.

“I’m more afraid of the judges than I am of crocs,” she quipped. But according to reports, the reptile lover will have one less judge to worry about. US Weekly reported that Len Goodman, who was with “DWTS” since its debut in 2005, won’t be back on the judges' panel.

"Len will not be returning as a judge this season on 'Dancing With the Stars' due to his schedule as a judge on ‘Strictly Come Dancing' in the U.K. and the birth of his new grandson," “DWTS” executive producer Rob Wade recently told the magazine.

But fear not! Just because Len won’t be assessing every move of the competitors doesn’t mean Grumpy Goodman won’t be making a few appearances throughout Season 21. "He still might be involved in the season at some capacity, but we will have to wait and see," Wade revealed.

Guess Irwin should start practicing her moves to “Crocodile Rock” -- pronto!

The remainder of the celebrity cast of “Dancing With the Stars” will be revealed on "Good Morning America" Wednesday, Sept. 2. ABC will air the Season 21 premiere on Monday, Sept. 14.
