Gemma Collins has been trying to sneak sweet treats into her camp while shooting the new series of 'Sugar Free Farm'.

The 'Only Way is Essex' star - who keeps making cameo appearances in the ITVBe show - has only just started filming the gruelling weight-loss programme but is already wreaking havoc for producers as she's been trying to bend the rules.

A source told Daily Mirror newspaper: "Some of the crew think Gemma is being a bit of a nightmare on the show. She has tried to bring in food which was taken off her and has been arguing with production crew."

And the 35-year-old reality TV beauty isn't just infuriating show bosses as she's also got on the wrong side of her co-star Ann Widdecombe due to her outrageous diva behaviour.

The insider explained: "At one point Ann Widdecombe lost her temper and branded Gemma selfish and impossible to work with because she wouldn't take part in a task. There have been fireworks and we are only just beginning."

Meanwhile, Gemma - who appeared in 'Celebrity Big Brother' earlier this year - sensationally quit 'TOWIE' last year but was seen gracing screens over the weekend when she rocked up to comfort her friend Bobby Norris over the death of his dog.

And now her fellow castmates are desperate for her to make a permanent return to the Essex-based reality show.

Chloe Sims told new! magazine: "I would love her to return to 'TOWIE' full-time. I didn't get a chance to find out the goss on her new fella, but she seems really happy."

'Sugar Free Farm', which sees six celebrities muck out animals and pick vegetables while following a strict sugar-free diet, is expected to hit television screens in January.
