PERSHORE'S Toyah Willcox is 25-1 to be the first to strip naked in I'm a Celebrity Get Me Out of Here.

And bookies Ladbrokes have also laid odds of 100-1 on the 1980s pop star stripping off while singing her hits in the jungle.

The odds have been set after day one of the celebrities' two week Australian trial, which saw tensions between Toyah and telly stunner Catalina Guirado set to grow.

Problems began when viewers voted for Catalina to do the second Bushtucker task - the Crocodile Leap Trail - where she will hang perilously low over a river of crocodiles to win food for the team.

She became decidedly snappy at the prospect and Toyah's reassurance she did not have to go through with the task did little to improve her mood.

Earlier, team leader and ex-football hardman John Fashanu endured the first Bushtucker Trial with seven different kinds of creepy crawlies - including crayfish, leeches and stink beetles - down his over-sized trousers.

He wisely called it a day when he saw the next container was filled with rats.
