The reality show told spinoff show Get Me Out of Here NOW that the Vicky viewers are seeing in the jungle is not the real Vicky.
He said: "It's not Vicky. She's playing a very safe game. I've known her for a long time and she's the most argumentative person I've ever met in my life. At the minute she's playing it very safe and trying to get everyone to like her."
Gaz said an example of this was Vicky playing it safe when it came to creating the immunity challenge teams, saying: "The Vicky I know would have mixed it up, put Lady C with Duncan, but she's playing a safe game."
He added: "The only person in there who could have a good argument with Lady C would be Vicky. I know that. I'm waiting for that to happen."
When host Laura Whitmore pointed out Lady C actually likes Vicky, Gaz replied: "Vicky can make anyone like her, though. She's very good but very bipolar as well, she can flip and kick off like that. That's the Vicky I'm waiting to come out. I just want her to go nuts and not play it so safe. I would love her to have an argument."
I'm A Celeb continues tonight on ITV.
