Apparently the former EastEnders actor is the reason why I'm A Celebrity... Get Me Out Of Here! spinoff show hosts don't find out who is entering the jungle until the last minute!
This year, it's Joe co-hosting the newly named Extra Camp alongside girlfriend Stacey Solomon, Vicky Pattison and comedian Chris Ramsey.
Talking about this year's lineup on Good Morning Britain, Stacey said: "We wish we knew! But because of Joe no one is allowed to know anymore!"
Joe explained: "I told my nan one year. She lives in a little place in Norfolk called Thetford. It all got back to London and the agent phoned up and now we don't find out until the day before the press finds out."
Actor Joe won the eighth series of I'm A Celeb in 2008, while Stacey triumphed in series ten two years later, and Vicky won the 2015 series last year.
"The jungle is amazing," said Joe. "I came from EastEnders and didn't think I'd get any acting work. The jungle opened a whole new world of other work."
Stacey agreed, saying: "It was the most amazing experience of my life. I absolutely loved doing it. Meeting all the people. And since I came out, I've had the time of my life."
When Susanna Reid pointed out Joe and Stacey had met via the jungle, Stacey laughed: "It's done so much for me!"
Cue Piers Morgan asking: "Are you [dating?] I didn't know that!"
I'm A Celebrity returns for its new series next month.
