The Hollywood stars left Jacqueline Jossa and Andy Whyment very star struck when they appeared in the jungle via a pre-recorded video during their Dingo Dollar challenge.
The challenge was a Jumanji theme - with both actors starring in the sequel The Next Level.
The Rock told the pair: “To win the dollars, complete three games. Then grab the red jewel that is yours to claim.

“If you escape with the jewel and place it into the light, then shout ‘Jumanji’, enter the shack for delight.”
Jacqueline and Andy appeared starstruck, with Andy quickly composing himself and telling his campmate: “Alright, calm down Jac, he’s not here, he’s in the TV.”
Jacqueline seemingly ignoring his advice squealed “he said ‘camp mates’”.
After completing their task The Rock returned to the screen with his co-star Hart.
The Rock said: “Congratulations Camp mates.”
Hart joined in: “You have placed the jewel into the light and Jumanji is completed.”

The Rock added: “In return, you have been awarded 100 dingo dollars.”
Hart concluded: “Please spend them wisely.”
Once more Jacqueline was left jumping for joy telling the fellow camp mates at camp that the actors now “know” her.
Social media reacted to the actress' reaction, with one writing: "Does Jacqueline think that the rock will actually be the dingo dollar prize??".
Later during Thursday's episode, the mood changed quickly as the camp mates were left in floods of tears after receiving letters from their loved ones.
The atmosphere quickly turned into an emotional one as each letter was read out with Caitlyn describing the moments as “lifting up the morale”.
Caitlyn’s letter from home was read out by Jacqueline: "You are doing such an amazing job in the jungle. Show these Brits that American Olympian endurance.
“The dogs and I miss you so much, we decorated the house but Baxter tore the lights off the trees already so it’s waiting for you to fix it."
I'm A Celebrity ends on Sunday night on ITV.
