Usain Bolt’s girlfriend is apparently used to sharing

Usain Bolt’s main squeeze back home will be upset — but won’t think he crossed the line for a series of post-Olympics romps in Rio, the track superstar’s sister predicted.

Christine Bolt-Hylton, 32, defended Bolt for celebrating his 30th birthday by making out with a brunette, twerking with another and then vaulting into bed with a third — who posted racy images of their tryst online.

“I’m sure Kasi will be used to it by now. She is used to seeing pictures like this,” Bolt-Hylton said of Kasi Bennett, the star’s Jamaican girlfriend of two years whom she believes he’ll marry.

But if some of Bennett’s social media “likes” are any indication, the nine-time Olympic gold medalist may have a few hurdles to clear with her.

She liked a tweet from a fan who wrote: “@usainbolt you traded your life with a #goddess, for a one night fling with someone who will never even come close.”

“People ask for pictures with him and he is always willing to have pictures. She is used to him being in the public domain,” she said, the Daily Mail reported.

Brazilian beauty Jady Duarte, 20, shared images over the WhatsApp chat app of herself canoodling with Bolt in his Olympic Village room.

“I don’t think anything happened between him and the Brazilian girl,” Bolt-Hylton added. “He loves Kasi too much to jeopardize the relationship. I’m looking at the pictures and it doesn’t look like he was doing anything with her.”

Asked if Bennett will be upset, Bolt-Hylton said: “The pictures are of a young girl. I know she will be upset. But she will talk to him and I know they can work their difficulties out.

“Usain doesn’t believe in cheating. … He has never done this before as far as I know,” she added. “When he was much younger he was popular with the girls but from when they have been together, he hasn’t done anything like that.”

Bolt should still apologize to Bennett for the bedroom pictures with Duarte, his sister said — adding that “Kasi was definitely OK” with the pictures that emerged from the private party at All In, a club in the Barra de Tijuca suburb of Rio de Janeiro.

Adding to the embarrassment, it emerged that Duarte was the widow of a Rio drug lord, Douglas Donato Pereira, known as Diná Terror, with whom she had two children.

Meanwhile, Bolt’s one-track mind was still evident Monday, when he was photographed with several scantily clad women at a London hot spot, the Mirror reported.

He set hearts racing at the Cirque le Soir club, where he took to the stage and serenaded his fans.

“We gave him the mic and he was telling everybody it had been his birthday a couple of days ago,” Yvette, a waitress at the club, told the Daily Mail.

“From about 1 until 3 a.m., people were buying him drinks — champagne, Sex on the Beach, Kamikaze shots — everybody was just appreciating him and celebrating his gold medals,” she said.
