Has Bolt proposed to his long-term girlfriend?

After sparking controversy with his late-night antics following his triumphant Rio Olympics campaign, legendary Jamaican sprinter Usain Bolt seems ready to settle down as he strongly hinted that he has proposed to long-term girlfriend Kasi Bennett.

The world's fastest man, currently vacationing with Bennett on the French Polynesian island of Bora Bora, posted a cryptic photo on his Snapchat account with the caption "she said yes", featuring a bride Emoji.

The couple have been together for nearly three years, but Bolt found himself at centre of a scandal after a picture of him in bed with a Brazilian girl went viral.

He was also spotted locking lips with another female in a nightclub in Brazil while celebrating his 30th birthday after the Games.

Bolt ended his illustrious track career after claiming an unprecedented 'triple triple' and his ninth gold in Rio de Janeiro last month.
