Katie Price has vowed to win 'I'm A Celebrity... Get Me Out Of Here!'.

The glamour model - who is expected to be a late entrant into the jungle-based reality contest some time this week - has warned fellow contestants she will be their "worst nightmare" when she arrives in camp.

She is quoted by Britain's The People newspaper as saying: "I'm coming here to win. All those who have come out against me won't know what's hit them.

"It's not the snakes, spiders and creepy crawlies they should be worried about. I can easily be their worst nightmare. I've never heard of most of them anyway which is probably why they are paying me so much more.

"I'll certainly use that to get their backs up if I have to."

The glamour model - who has three children, Harvey, seven, Junior, four, and Princess Tiaamii, two - singled out former pin-up Sam Fox as her biggest rival on the show.

She reportedly told a friend: "There's only room for one glamour queen in the camp and that's me.

"I know Sam's 43 now and still has a fantastic body but she won't be able to compete with mine. "I'll get in the shower with Sam and let the viewers decide which breast is best."

'I'm A Celebrity... Get Me Out Of Here!' starts on ITV1 tonight (15.11.09).
