With his debut he will bring real Hollywood star power to the South African jungle.

A-listers are reportedly “desperate” to appear on the show because of their friendship with the handsome wildlife warrior.

“There are some celebrities we ask every year, and maybe stars like Melissa or Jean-Claude Van Damme will finally say yes this year.” “It's our year to catch some of these beluga whales.”

Back in October, Chron Australia revealed that Robert was set to rake in almost half a million dollars for his month-and-a-half foray into the wilds of South Africa.
