The Jamaican track and field great, and his partner, Kasi Bennett, announced the birth of their twin boys, Thunder Bolt and Saint Leo Bolt, in a social media post on June 21. 

The post shows a photo of Bolt, Bennett, their one-year-old daughter Olympia Lightning, and the newborn twins.

Similar to his sister’s, Thunder’s name is a cute play on words. Saint Leo is Usain Bolt’s middle name. 

The post did not say when the twins were born. The pregnancy was a surprise, as neither Bolt nor Bennett revealed the pregnancy in previous posts.
