Usain Bolt is now a father of three.

The eight-time Olympic gold medalist and his longtime partner Kasi Bennett celebrated Father's Day on Sunday by announcing two new additions to their family: twins Saint Leo Bolt and Thunder Bolt. The couple are also parents to daughter Olympia Lightning Bolt, who was born in May 2020.

Bolt, 34, retired from sprinting in 2017. This summer's Tokyo Games will be the first Olympics since 2000 that he hasn't competed.

"I'm definitely excited to just be in the stands," Bolt told CNN's Matias Grez in March. "I've never got an opportunity to really watch Olympic Games, to either go (watch) swimming, the soccer or just to see all the events. So I'm excited to actually get the chance to really experience Olympics like a true fan."
