Rebecca Adlington’s exemption from Bushtucker Trials on I’m A Celebrity…Get Me Out Of Here! is mystifying viewers.

The Sun reported that the Olympic star has been deemed unable to compete in three challenges on medical grounds.

Her finance, Harry Needs, who has arrived in Australia, has even had to deny that the swimmer is pregnant, tweeting: “I can honestly say hand on heart, she’s not. Unless something went on in the jungle without me.”

He added: “Exemption from trials isn’t a choice, by the celeb but by the doctor.

“Trust me @BeckAdlington is a tough cookie, she would be up for and give anything a try… She eats Bovril for crying out loud.”

He tweeted: “If It wasn’t something serious then obviously she would be straight in there eating a cockroach.”

Some viewers have complained about special treatment, but it is thought that the Olympic swimmer, who burst into tears while saying she felt self-conscious about her looks, could suffer from extreme claustrophobia.

Meanwhile, Amy Willerton’s dad has said he is not hoping for romance between his daughter and Joey Essex – because the model usually goes for ‘intellectuals’, according to the Daily Mirror.
