Jady, who was also at the Rio hotspot, describes how Bolt sent security over to get her attention – but she did not know who he was!
The Jamaican sprinter wrote himself into the history books by winning the triple-triple in Rio, taking gold in the 100metres, 200metres and 4x100m relay.
Bolt, has a girlfriend of two years at home in Jamaica who he calls his ‘First Lady’.
Speaking to local newspaper Extra, Duarte said that Bolt sent security over to get her attention.
She said she hadn’t realized that she was with a famous athlete and described their nocturnal encounter as ‘normal’ and ‘not a big deal’.
‘He sent a security call me, talk quickly. But at the time did not even know it was him, because they were like many Jamaicans,’ she said. ‘It was not a big deal. It was normal.’
Among the photos of Duarte with Bolt was a picture of a 100 Euro note – but she said: ‘No way, he did not pay me anything. I received no money.’
Duarte, a student from Rio, told Extra that she is upset about the publicity she has received since the pictures emerged, adding: ‘It’s very negative. I never wanted to be famous, I’m dying of shame.’
