He's one and done! While Robert Irwin received rave reviews for his co-hosting on this season of I'm A Celebrity... Get Me Out Of Here!, a TV insider tells Woman's Day he won't be back next season!

"As Julia's sidekick, the TV natural has delivered in spades," says the source. "His easygoing and faultless live TV skills have won over the nation. But his career at Ten will only be short-lived, and he is heading back to Seven."

According to the network spy, Robert cleverly signed on for only one series in Africa.
