Olympic champion and his partner, Usain Bolt have welcomed twin boys, named Thunder Bolt and Saint Leo Bolt.

Bolt, 34, announced the news on Instagram on Father’s Day, with a lightning bolt emoji next to each of his children’s names.

The champion posted a photo of him and partner Kasi Bennett, with their twin boys and one-year-old daughter Olympia Lightning.

The couple did not say when exactly the twins were born.

Olympia Lightning was born in May 2020, and her name was announced publicly two months later.

Bolt, a Jamaican sprinting icon, retired from athletics in 2017 and still holds the 100m and 200m world records, making him the fastest man in history.

He is also the only man to have won three 100m Olympic titles and 23 major gold medals during his career.
