I'm A Celebrity...Get Me Out of Here! star Russell Watson revealed that he has lost almost 20 lbs in just two weeks while starring on the ITV show.

The 54-year-old English tenor - who has become the latest star evicted from Gwrych Castle alongside Jessica Plummer - admitted that his pants are now falling down after shedding so much weight.

Speaking to the MirrorOnline alongside other journalists, Russell revealed that he was eating about a fifth of his normal calorie intake while he appeared in the ITV show.

Russell went on to explain that even his red camp trousers were starting to feel loose within the first week.

"I had my leggings on most of the time and then I decided its probably right to put by red pants on after about a week," Russell explained.

"The thing is, once I put my red pants on they were falling down my backside.

"I've lost nearly 20 pounds in two weeks in there. The weight literally fell off me so I was quite pleased about that because I was a big unit when I went in there.

"I put my clothes on today and my pants are falling down. Had to stick like two belts on to keep them up," Russell added.

As for the camp eating habits, the television star explained that he was still juggling a concoction of medicines while also struggling with a low calorie intake.

"I was eating a fifth of my calories in there, like really low calories so I got through it and I feel really proud of myself," he added during the interview.

Although he struggled to fit into his clothes, Russell did reveal that the camp were provided with a change of clothes and had their garments washed during their time in the camp.

However, he also pointed out that it was so cold in the castle and outside that the campmates would often layer up and wear three pairs of socks just to keep warm.
