Some photos of Jamaican sprinter Usain Bolt with a student, described as intimate," have surfaced online, just when reports are doing the rounds that he would be marrying his girlfriend, Kasi Bennett. 

The photos, which appear to show Bolt with a 20-year-old girl, have gone viral on Brazilian websites. The 20-year-old Jady Duarte shared her WhatsApp photos that show her embracing a bare-torsoed Bolt, who is set to marry girlfriend Kasi Bennett.

Duarte shared the photos with her friends, after which it appeared on several Brazilian websites, including Extra Globo. In one of the photos, Duarte is seen wearing a white top, while in another photo Bolt is seen giving her a kiss on her cheek, Daily Mail reported. The intimate photos were released on Sunday when Bolt celebrated his 30th birthday.

Talking to a local newspaper, Duarte said that Bolt sent security to call her, but at that time she didn't know who he was. She described her encounter with Bolt as normal and said it was not a big deal.

"I just sent it to the group of my girlfriends' girls, now you see. Just I sent and said who only saw the Olympics will know who is," she told Extra.

Duarte was not the only woman with whom Bolt partied on Sunday. He was seen twerking with another woman at the Barra de Tijuca hotel in the suburb of Rio. A video of Bolt twerking enthusiastically has also been doing the rounds on social media.

Meanwhile, Bolt's sister Christine Bolt-Hylton revealed to the Sun that the Olympic star would propose to her when he returns home. Christine said that Bolt and Bennet have been dating for two years now.

"I've met her and she's lovely – she's perfect for Usain. I would say that there's a very strong possibility they'll get engaged when he comes home. I've talked to Usain about starting a family and he says he wants to, and I'm sure he will now he's achieved so much," Christine told the Sun.
