The mortifying moment The Block’s Jess Eva wets herself during a challenge on I’m a Celebrity… Get Me Out of Here!

Former Block star Jess Eva has ventured into the Australian bush on I’m a Celebrity… Get Me Out of Here!

But on Tuesday, the Triple M radio host was left mortified after wetting herself during a challenge to rescue camp newcomer Robert ‘Dipper’ DiPierdomenico.

She shared an IGTV video of herself and former Collingwood star Travis Varcoe trying to retrieve a key from a dark room to unlock footy legend Dipper.

Oh dear! Former Block star Jess Eva was left mortified after she wet herself during a challenge on I’m A Celebrity… Get Me Out Of Here! in which she had to retrieve a key from inside a dark room to unlock and rescue camp newcomer, retired AFL star Robert ‘Dipper’ Dipierdomenico

But it wasn’t without its challenges, as Jess and Travis had to deal with boxes filled with ‘creepy crawlies’ and gunshot sounds ringing around the room.

Jess claimed she ‘didn’t realise’ the sound effects were part of the task, and this heightened tension cause her to urinate.

The mother of two admitted on Instagram: ‘Okay, I weed myself! Actually not that uncommon after a couple of kids.’

Whoops! She worked alongside former Collingwood player Travis Varcoe to find the key in a room with fake 'creepy crawleys' and pretend gunshots being fired. Unfortunately, this heightened tension in the room caused Jess to accidentally urinate on herself

She added: ‘First time I’ve weed myself whilst holding the arm of a retired Collingwood legend Travis Varcoe though, so that’s new.’

‘Always wondered what I would do in a life or death situation. Turns out I’d fall to the floor and wee my pants,’ she added.
