The former Miss Universe Australia, who was a finalist in last year's season of the reality television show, said that she is supporting Can of Worms host Ian Dickson and Australia's Next Top Model judge Charlotte Dawson.
Campbell told The Daily Telegraph: "I think Dicko has a really good shot at winning - he seems level-headed and would have great contacts to call upon in the challenges.
"Charlotte could also be very good. I think there could be some 'incidents' with her because she's very honest and that might not sit too well with some."
Campbell's fellow contestant Deni Hines was accused of bullying her and Polly Porter last year, after getting into arguments with them both during challenges and later threatening to physically hurt Campbell.
Among the stars taking part in this year's Celebrity Apprentice are television personality Patti Newton, Baywatch actor David Hasselhoff, former footballer Jason Akermanis, waterskier and model Lauryn Eagle and MasterChef contestant Marion Grasby.
