Modahl is one of 10 celebrities living in the Australian rainforest

William Hill has offered odds of 10/11 for Modahl to go, followed by former BBC Radio 1 DJ Mike Read on 9/4.

All 10 participants are together for the last time on Monday as they await the first public eviction vote.

More than 10 million viewers watched Sunday night's episode on ITV1, according to unofficial figures.

The show has kept viewers hooked with a series of "Bushtucker trials" in which contestants have faced various nature challenges, some involving jungle wildlife.

In Sunday's episode, model Jordan and former Atomic Kitten singer Kerry McFadden set about eating grubs, worms, cockroaches and fish eyes in order to win meals for the camp.

On Monday's show Alex Best, estranged wife of former footballer George Best, will try to crawl through five tanks containing snakes and spiders.

Jordan and former punk singer John Lydon are frontrunners to win the contest, with aristocrat Lord Brocket third favourite with bookmakers.

Contestants, who also include former Royal correspondent Jennie Bond and singer Peter Andre, are spending up to 15 nights in a remote camp in the Australian rainforest to raise money for their chosen charities.
