The news was first announced on Monday by Jamaican Prime Minister Andrew Holness on Twitter.
“Congratulations to our sprint legend Usain Bolt and Kasi Bennett for the arrival of their little girl!” he said in a tweet.
Bolt, 33, who retired from athletics in 2017, is still the fastest man in history. The world record of 9.58 seconds which he set in the 100m at the Berlin World Championships in 2009 is still valid, as is his world record in the 200m in 19.19 seconds, also achieved in Berlin.
He completed the historic “triple triple” at Rio 2016 by winning gold in the 100m, 200m and 4x100m relay at three successive Olympic Games. However, in 2017 Bolt was stripped of his 4x100m gold medal at the 2008 Beijing Games after teammate Nesta Carter tested positive for a prohibited substance.
The Jamaican ran his last competitive race at the 2017 World Championships in London, where he finished third in the 100m. He had a brief football career, joining the Australian team Central Coast Mariners in 2018.
Bolt scored two goals in his debut in a pre-season friendly, but left the club before making an official appearance after the two sides failed to reach an agreement.
