Former boxing promoter Frank Maloney (61) is undergoing a sex change, according to reports.
Maloney, who guided Lennox Lewis to the world heavyweight title, has told how she now lives as a woman called Kellie.
"I wasn't born into the right body, I have always known I was a woman. I can't keep living in the shadows," she said.
"At this very moment I am preparing to live the rest of my life as a single person."
She says the boxing community can think whatever it wants about her now.
"I hope society will be open minded. I know I could have done my job in boxing as a female."
Maloney announced his intention to call time on his 30-year career with immediate effect last October.
His decision brought an end to a colourful career which saw him guide Lewis to glory despite memorably being derided as a "mental midget'' by US promoter Don King.
Lewis took to Twitter when Maloney retired to say: "Big up 2 @FrankMaloney on a massive career in the fight game. Gonna miss those Union Jack suits. All the best to u and urs.''
Maloney's garish suits might have earned him fame as Lewis's sidekick, but his jovial image belied a shrewd boxing brain as he swerved King's obstacles to lead Lewis to the top.
"Boxing has given me some great times but it's not the same business I grew to love any more. The characters have gone. 'I am going to go travelling through Europe with my two Airedales and see how far I can get," Maloney said.
