Stunning model Kelly Brook enjoys the beach

Stunning model Kelly Brook, recently seen enjoying her newly single status in St Tropez, France, has just signed up for TV reality show I'm A Celebrity.

It will be back to work soon - in the Australian rainforest - as the TV presenter faces the endurance test of a lifetime, the Daily Star reports.

Brook, who has just split from 42-year-old fiancé Billy Zane, saying she is 'too young to marry' at 28, has been frolicking in the mediterranean resort with a friend.

The ITV show throws celebs together, as they swap lavish lifestyles for a basic existence in one of the world’s most inhospitable climates.
Bed will be a hammock, and to earn more than the basic rice and water dinner, Brook will have to undergo challenging endurance tests.

And it's not just the physical workout - Brook's Australian adventure looks likely to be an emotional rollercoaster too. Past series have seen Jordan and Peter's romance take shape, and petulant posing from former sex pistol Johnny Rotten.

It remains to be seen how Brook will fare, swapping a luxury lifestyle and a film star fiancé for life in a jungle clearing.

But with scorpions, snakes and poisonous spiders for companions, perhaps the jungle won't be such a change from Hollywood after all.
