Mike Tyson has said he had no regrets as he launched a boxing brand in his name in central London.
The former heavyweight champion, who has served a jail sentence for rape, said the negative experiences of his life have shaped him, and without them he would be "miserable".
Speaking at the Lillywhites sports department store, he told reporters: "If I had regrets I wouldn't have the purity of the happiness that I have now."
The new Mike Tyson Collection features T-shirts and boxing equipment influenced by his career and body art.
Tyson has this year taken to the stage with his show Mike Tyson Undisputed Truth, which saw him tell the story of his often troubled life.
The explosive boxer was the youngest man ever to become heavyweight champion of the world after he beat Trevor Berbick in 1986 when he was just 20.
But throughout his career he also courted controversy. He bit opponent Evander Holyfield's ear, went bankrupt, lost his four-year-old daughter in a tragic domestic accident, and was jailed.
