Singer Simon Webbe needed oxygen after a water challenge on I'm A Celebrity... Get Me Out of Here.

Webbe, who has been ill in recent days, stepped up to do the Bush Tucker Trial called Last Gasp.

Arriving at the challenge he confessed to presenters Ant and Dec that he had a fear of water.

"I don't swim at all but didn't want to say anything in camp," he said.

Under the water were bubbles containing stars and guarding them were jungle critters including water spiders, eels and crocodiles.

Gaining six out of seven stars, Simon headed out of the pool.

Having faced his fears Webbe received some oxygen from the medics on site.

He revealed: "It's the hardest thing I've ever done in my life, anything after this is a breeze."

Asked if he had conquered his fear, Webbe replied: "No".

The singer said: "I'm shaken up to be honest, I think I hit my head as well.

"I'm still a bit dazed from it all and I can't really speak, I don't know if I'm in shock."
