But that didn't stop Usain Bolt falling for sexy 22-year-old Megan Edwards in a romance that is said to have inspired his triple gold-winning performance at London 2012, it was reported in the Sun on Sunday.
Bolt, who holds the 100m world record with a time of 9.58 seconds, swapped numbers with Megan when they appeared on the catwalk together to unveil Jamaica's team kit earlier this year.
It is believed they went on a series of secret dates during the Games as 26-year-old Bolt powered his way to victories in the 100m, 200m and 4x100m relay.
Megan, a junior athlete at Dartford Harriers Athletics Club, then celebrated his unprecedented success at a party in London's Brick Lane, where Bolt whipped the crowds into a frenzy with his DJ-ing skills.
A source told The Sun on Sunday: 'It was crazy. Everyone was trying to get a piece of him - especially the girls. But Usain only had eyes for one girl that night and that was Megan. She was by his side all night.'
They later went to West End club Movida along with Bolt's teammate Yohan Blake, boxer Lennox Lewis and hip-hop artist Nas.
A friend of Megan said: 'Megan was in her element. She's really smitten with Usain. It's nothing too serious at the moment as he's jetting off all over the world - but they are two adults having fun.'
Bolt had ordered a £50,000 bottle of champagne, which apparently featured in a picture of the pair uploaded on Megan's Facebook page.
On another picture she is said to have commented: 'Me n my Baby!! The Bolt!! X'.
Bolt, who earns around £13million a year in sponsorship deals and appearance fees, met Megan around three months ago at the photoshoot.
His agent told MailOnline: 'We do not make any comments on the privates lives of our athletes.'
Megan told The Sun she was not prepared to talk about 'us two'.
