Prince George, Princess Charlotte and Prince Louis have been praised by Robert Irwin for helping him choose the “perfect” name for a joey kangaroo.

The young royals named the baby eastern grey kangaroo “Cwtch”, which is Welsh for cuddle.

“The absolute perfect name for a joey kangaroo, 'cause at this age they love a cuddle, and they spend most of their time inside that pouch with their mum,” said Irwin.

"Cwtch is now proudly part of our family here at Australia Zoo,” he beamed as he thanked the family for their support for the zoo’s wildlife conservation efforts.
