Boxing legend Ricky Hatton is said to be "devastated and distraught" after being secretly filmed allegedly snorting cocaine.
The former world champion, nicknamed The Hitman for his knock-out punching, is alleged to have used "industrial quantities" of the drug by the News of the World.
Hatton, 31, is captured in video footage appearing to use a credit card to cut lines of cocaine before snorting them through a rolled-up bank note.
His spokesman Max Clifford said: "I have spoken to Ricky, he is very upset and very subdued, very flat.
"He feels he's let everybody that matters down badly, his friends, his family, his fans and of course most of all himself, that he is, in his own words, he's been in a bad place for some time, probably before even his last fight and obviously he's really upset about what has happened but he totally takes responsibility, takes the blame, 'It's all down to me'.
"He just wants to let everybody know how he feels, he's got to sort himself out.
"I think it is fair to say, friends and family have been trying to warn him in recent times, for the last few months and now they are all hoping this situation will bring him to his senses.
"I think obviously everybody is hoping some good will come out of this. He feels devastated and we all hope this will be the wake-up call."
The News of the World states the video footage was captured over several hours at a Manchester hotel two weeks ago while Hatton was on a night out with friend Emma Bowe, 29, the Irish national senior women's boxing champion. She told the paper Hatton also binged on drink by sinking 11 pints of Guinness, vodka, wine and sambuca during the night out.
"I'm only talking about this because Ricky is a danger to himself. If he carries on like this he'll kill himself," she is quoted saying.
