Usain Bolt may be engaged to his longtime girlfriend, if his latest social media posts are any indication.

On holiday on the Tahitian island of Bora Bora with girlfriend Kasi Bennett, Bolt has posted a wide-smile pic of himself with Bennett with the caption: “she said yes!”

The post comes after the nine-time Olympic gold-medal winner was filmed and snapped with a raft of young and sexy beauties at the end of the Games in Rio, late last month.

Bolt was spotted dirty dancing in a Rio bar with a British model, who came back to the athlete’s hotel with seven other women to party on.

Pictures also circulated of Bolt in with a Brazilian woman who is believed to be a mother and the widow of a drug lord known as Diná Terror, and of him kissing and canoodling with Brazilian student Jady Duarte.

But Bolt’s elder sister, Christine Bolt-Hylton, previously told British media that Bennett was used to her brother’s antics and that the couple were a solid item.
