Usain Bolt shares adorable picture of baby daughter for the first time and reveals her name is Olympia Lightning

USAIN BOLT has shared an adorable first picture of his baby daughter, revealing her name - Olympia Lightning.

The Jamaican sprint star, 33, and long-time partner Kasi Bennett welcomed their baby girl in May.

But until now, the name - apt for the daughter of the fastest man who ever lived and eight-time Olympic Games gold medallist - had been kept a secret.

The happy couple hosted a luxury gender reveal party in March which featured fireworks and a huge celebrity guest list, after which Bolt told fans he is set to become a "girl dad."

The sprint legend has been dating Bennett, four years his junior, since 2014 but the pair only went public in 2016.

Bolt confirmed his girlfriend was pregnant in January when he posted an Instagram photo of her in a flowing red dress cradling her baby bump.

In the caption, he added the words: "'I just want to say a KING or QUEEN is about to be HERE."

Bolt retired from the track after the 2017 World Championships in London after suffering a hamstring injury in his final race.

The 11-time world champion remains the only man in history to win gold medals at three successive Olympics, in 2008, 2012 and 2016.

The Jamaican also holds world records in the 100m and 200m events having clocked 9.58 seconds and 19.19 seconds respectively at the 2009 World Championships in Berlin.

Bennett, meanwhile, lives in Jamaica, is an avid social media user and fashionista - currently boasting 345,000 followers on Instagram.

And it would seem the couple are in no rush to force little Olympia Lightning into athletics.

In the past, Bolt has admitted the burden of living up to his legacy may even actively discouraging his kids from the sport.

Bolt revealed: "That's going to be hard for my kid.

"If they want to do it, I'm fine with it.

"But initially, I'm going to say don't do it, because I know the pressure that will come along with it."
