Costa Rican-based Eric was pictured at Brisbane International Airport on Sunday (23 November) as former Playboy model Kendra continues her stint in the jungle.
He told the Daily Star that he has faith in Kendra to get over her fears quickly, claiming she comes from "jungle stock" as he lives in Costa Rica.
He said: "She was just down in Costa Rica at my house a little while ago and we have every animal, every insect, everything you can imagine in the jungle. I saw her fear, but she's getting over it pretty quickly."
Viewers of Kendra's reality show Kendra On Top recently saw the star reuniting with Eric in Costa Rica for the first time in two decades.
"I am so excited that I did that for myself as a human being," she said at the time. "And we're still in contact. We're talking almost every day, emailing each other almost every day, and sending each other photos."
Eric added to The Mirror that he believes Kendra could win I'm A Celebrity, becoming the first American to ever be crowned Queen of the Jungle.
"If any American can do well, Kendra can. Especially with her spirit, her sense of humour and her strength."
Kendra's had a tough time in the jungle having to take on three consecutive Bush Tucker Trials, but got a break last night when presenter Melanie Sykes was chosen to do the latest trial instead.
I'm A Celebrity airs nightly on ITV.
