According to The Sun, the glamour model will receive £350,000 for her stint in the jungle, while the other celebrities are said to be earning around £65,000 each.
A friend of another unnamed contestant said: "This really is taking the mick. We were pushing for more cash but were told things were tight this year. Now we know why.
"If ITV are looking for trouble in the jungle, they will certainly get it once she turns up."
Price has reportedly flown to Los Angeles for a three-day stopover before arriving in Australia, supposedly later than the other contestants.
Her ex-husband Peter Andre reportedly turned down an offer to return to the programme where the couple met and is said to be upset at Price not making childcare arrangements with him before deciding to enter.
