Ian Thorpe, Australia's most decorated Olympian, revealed he was gay in an emotional television interview on Sunday, ending years of speculation about the champion swimmer's sexuality.
The five-times Olympic gold medallist made the admission to British journalist Michael Parkinson in a pre-recorded interview on Australia's Channel 10 in which he shared his relief in freeing himself from living "a lie".
"I've thought about this for a long time. I'm not straight," the 31-year-old said, struggling to hold tears back.
"And this is only something that very recently, we're talking the past two weeks, I've been comfortable telling the closest people around me, exactly that.
"I've wanted to (come out) for some time but I couldn't, I didn't feel as though I could.
"What happened was I felt the lie had become so big that I didn't want people to question my integrity."
One of Australia's favourite sons, Thorpe had long denied he was gay and wrote in his 2012 autobiography 'This Is Me' that he was heterosexual.
"For the record, I am not gay and all my sexual experiences have been straight," Thorpe wrote in the book. "I'm attracted to women, I love children and aspire to have a family one day."
Smartly dressed in a navy blue coat and sporting a face of stubble, Thorpe said he had long battled to accept his sexuality, and might have come out earlier if he had not been constantly questioned about it from the age of 16.
"The problem was I was asked at such a young age about my sexuality. I went to an all boys school... so if you're accused of being gay, the first answer is no and you get ready for a fight," he said.
Being called a "faggot" and other homophobic taunts by members of the public had also not helped.
However, he admitted a big part of his reticence was that he worried that being gay would not fit into his image as "Australia's champion".
"Now it'll be something that I work on with a doctor," he said.
"This trying to live a lie which I was doing... but I was already living somewhat of a lie in my life because I was trying to be what I thought was the right athlete by other people's standards.
WAVE OF SUPPORT
"I wanted to make my family proud, I wanted to make my nation proud. Part of me didn't know if Australia wanted its champion to be gay.
"People will criticise me, some people won't like the idea other people may applaud me for it, but it's me."
Thorpe's revelations sparked a wave of support from fellow athletes, celebrities and gay activists on social media.
"I can totally understand how difficult this whole process has been for him," Australian Olympian Matthew Mitcham, who came out before winning a diving gold at the 2008 Beijing Games told Sydney newspaper, the Telegraph.
"I really hope this process gives him some peace and that the media and the public give him the same respect and the same overwhelming support I received in 2008."
Singer Ricky Martin tweeted: "Congrats @IanThorpe! Brave man! Happy for you! Millions appreciate what you've done! Proud of you! #SelfLove."
After shooting to fame when he won the 400 metres freestyle at the 1998 World Championships in Perth, Thorpe won three gold medals at the 2000 Sydney Olympics but was soon taking medication and binge drinking in a long battle with depression.
Thorpe's revelations come only months after checking in to rehab after being found disoriented in Sydney, later attributed by his manager to a cocktail of anti-depressants and medication to treat an injured shoulder.
The man nicknamed "Thorpedo" was rushed to hospital in April after contracting an infection following shoulder surgery and is unlikely to swim competitively again.
Thorpe won two golds at the 2004 Athens Olympics but shocked by quitting the pool in 2006 at the age of 24, saying he was fed up with being a "performing seal".
He later revealed he had pondered ways to kill himself during the depths of his depression.
He returned to the pool in 2011 in a bid to qualify for the London Games but failed at national trials the following year.
Thorpe told Parkinson he regretted pulling the pin early in his career.
"Now I wish that I hadn't but it's what I needed to do," he said. "I could have (won more medals)."
