After Brazilian student Jady Duarte uploaded pictures of herself cuddling with Jamaican sprinter Usain Bolt on bed, it was obvious that the 30-year-old had cheated on his longtime girlfriend Kasi Bennett (pictured above). The indications was further fueled after Bolt was pictured grinding hard and kissing an unknown girl inside a nightclub days before the end of the 2016 Olympics, however, his big sister, Christine Bolt-Hylton, does not believe Usain had cheated - and didn't see his relationship with Kasi crumbling.
"I'm sure Kasi will be used to it by now. She is used to seeing pictures like this. People ask for pictures with him and he is always willing to have pictures. She is used to him being in the public domain.
''I don't think anything happened between him and the Brazilian girl. I'm looking at the pictures and it doesn't look like he was doing anything with her.
"Usain doesn't believe in cheating. Normally when we speak he sees he is against stuff like that. He has never done this before as far as I know."
