Andrew Holness, the prime minister of Jamaica, was the first to announce the exciting news that Bennett had given birth back in May, tweeting, "Congratulations to our sprint legend Usain Bolt (@usainbolt) and Kasi Bennett on the arrival of their baby girl!"

The proud parents revealed back in January that they were expecting a child together. Bolt shared the happy news on Instagram at the time, alongside a stunning shot of Bennett showing off her bump in a red gown.

"I just want to say a KING or QUEEN is about to be HERE," he marveled.
