Calum's return was revealed at the end of last night's (June 25) episode on ITV2, and viewers will soon see the Celebrity Big Brother star return to his old stomping ground.
Although he won't be going in as a contestant, Calum will be sharing his experiences with the current islanders.
"I can't wait to come back," he said. "If I can go in there and just share my experience with everybody else to make sure everyone has the best time they possibly can.
"I'm looking forward to getting amongst it."
Calum, who is dating model Ianthe Rose Cochrane-Stack, confirmed to fans that he was "very much in love" after being asked if he was going to pair up.
He told one fan: "It's a guest appearance my dear," and he said to another: "Not to pair up babe I have an amazing mrs, [it's to] share my experiences."
Hands up, who's excited?!
Calum appeared on Celebrity Love Island in 2005 and 2006, where he became the winner in the second episode. More recently, he came in third place in the 15th series of CBB, which was won by Katie Price earlier this year.
