She claimed she was seeking help for her anorexia and was remaining positive despite a relapse, but devastated Big Brother star Nikki Grahame admits she is losing her battle with the disorder.

Reality TV star Nikki has spoken extensively about her body troubles but, despite being hospitalised due to the condition in the past, had managed to overcome her woes.

However, pictures of the former Big Brother housemate looking painfully thin recently emerged, prompting 5st 7lbs Nikki to admit she is suffering once again.

A tearful Nikki told Heat: "I'm losing my battle again. I was so positive a few months ago. I was winning and had put on half a stone. I can't let myself go back to what I was, but I'm smaller than I was when I checked out of the clinic, back when I was really ill."

Nikki was regularly attending body awareness sessions and had started to gain weight but, after a holiday to Australia with her mother earlier this year, her weight started to plummet.

The star has suffered with the disease since childhood but, despite her past experience, feels unable to stop punishing her body.

She said: "At the moment, I have to work out twice a day. If I don't, my head is just racked with guilt. And I weigh all my food on scales. I'm currently on about 1,200 calories a day, when really I should be on over 2,000. I'm punishing my body. I can't stop but I'm getting help."

Sadly, Nikki has accepted she will battle the debilitating disorder forever but wants nothing more than to recover and gain weight.

She said: "It's something I will battle all of my life, but I want more than anything to get it under control."
