This year's 'Celebrity Big Brother' is turning out to be quite the firestorm with multiple walk-outs, immoral behaviour and full-blown rows happening left, right and centre. If housemates didn't think things could get any worse, they could be about to be proved very wrong by the arrival of TV nutritionist Gillian Mckeith.

Reports have claimed that McKeith, who's most famous for her diet show 'You Are What You Eat', will return to reality TV by raising hell in the Big Brother house, though not as a contestant. She will apparently show up to teach these indulgent stars some discipline, by forbidding alcohol, cigarettes and sugary food. Basically banning everything that's keeping the celebrities sane after a hectic three weeks confined together with nothing but each other for entertainment.

She'll be lucky to get some of the housemates to play ball, of course, and can she really enforce such stringent measures on these hot-headed roomies? It would be slightly hypocritical of her to criticise those who refuse to take part, given that she became the first person ever to refuse every single Bushtucker Trial that she was faced with while appearing in 'I'm A Celebrity... Get Me Out Of Here'.

We also hope that McKeith, if she really is going to appear on the show, doesn't take things too far by examining the celebs' lavatory deposits and reiterating why she earned the nickname Dr. Poo. 

According to the Daily Express, Channel 5 confirmed the news in a statement. 'Tonight, LIVE on Celebrity Big Brother, holistic food & lifestyle guru Gillian McKeith, will pay an unexpected visit to the Big Brother house', it read. 'Over the next few days, the celebrities will be put to the test in the ultimate January detox as prescribed by Gillian.'

Luckily, McKeith won't be bumping into any of her fellow jungle friends, though a few of the housemates have appeared on previous and subsequent series of 'I'm A Celebrity': Darren Day, Danniella Westbrook, David Gest and Gemma Collins.
