A student has shared photos of what appear to be her in bed with Olympic legend Usain Bolt.

Jady Duarte, 20, posted pictures to WhatsApp which seem to show the Jamaican sprint king, who has a long-term girlfriend, cuddling and kissing her.

Usain Bolt appears to hug 20-year-old student Jady Duarte from behind in one snap. Bolt appears to kiss Jady Duarte on the cheek in another picture despite it being revealed by the Sun on Sunday he has a girlfriend.

In one photo a topless Bolt appears to hug Jady, wearing a white vest, from behind while the other looks like he is kissing her on the cheek.

The pictures were shared by the Brazilian student and have appeared on several news outlets in her home country including El Globo.

Bolt turned 30 on Sunday and celebrated by partying until the early hours of the morning at All In, a club in the Barra de Tijuca suburb of Rio.

The Jamaican sprinter wrote himself into the history books by winning the triple-triple in Rio, taking gold in the 100-meter, 200-meter and 4x100-meter relay.

And throughout his post-Games celebrations Bolt, who The Sun on Sunday revealed has a girlfriend of two years, was recorded dancing and grinding on fellow party revellers at the De Bracos Albertas club.

But Duarte, who was also at the Rio hotspot, has since admitted she is "dying of shame" after her pictures went viral.
