"Yes, there are going to be animals at Bindi's wedding, it's going to be very exciting," Robert said.

He added with a laugh: "And maybe some crocodiles!"

Bindi, 21, also recently revealed that she will be walking down the aisle with a koala.
Speaking on Good Morning America last month she said: "I'm not sure how many people have walked down the aisle with a koala," she said.
"But we may be setting some new trends for weddings from here on out!"
