Sprinter Usain Bolt has announced about his newborn twin boys named ThunderBolt and Saint Leo Bolt by posting an Instagram post on fathers day.

But the couple hasn’t confirmed when exactly the twins were born.

He has posted a photo of him and his wife Kasi Bennett with their twin boys and one-year-old daughter Olympia Lightning with a lightning bolt emoji next to each of his children’s names in the post.

Bolt retired from athletics in 2017 and still holds the 100m and 200m world records.

He is also the only man to have won three 100m Olympic titles and 23 major gold medals during his career and it had made him the fastest man in history.
