The fastest man in history took to social media to announce the news his partner Kasi Bennett is expecting their first child.
The sprint legend, 33, posted a stunning picture of pregnant Kasi, 30, – who he calls his ‘first lady’ – in a flowing red dress alongside a typically witty caption.
It read: “I just want to say a KING or QUEEN is about to be HERE. @kasi__b.”
Kasi also shared the happy news on her own social media platforms and fans were quick to flood the replies with well wishes.
The pair have been together since 2014 but only went public in 2016.
Kasi lives in Jamaica and is nearly four years younger than the Olympic sprinter.
She stands at 5ft 3in which is more than a foot shorter than her other half who towers at 6ft 5in.
Kasi is an avid social media user and fashionista, currently boasting 285,000 followers on Instagram.
Bolt is an eight time Olympic gold medallist having won top prize in the 100m, 200m and 4X100m relay at three different games.
He wiped the floor with the competition in 2008 in Beijing, 2012 in London and most recently the 2016 Olympics in Rio.
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.
Although he claimed Olympic glory for the last time in Rio, he also made the news for the wrong reasons after a romp with Brazilian student Jady Duarte.
Only a couple of months earlier, Bolt had gone public with his relationship with Kasi.
And in a 2016 interview with The Telegraph, when asked about his love life the athlete admitted to having a girlfriend of two years.
He said: “But I’m not going to tell you who she is, I want to keep it small for now, because I know when it gets out there’s going to be a lot of things to say, and I told her she can’t handle it.
“Because I’ve been through the media. I understand how you guys are – especially the British media.”
Despite this, Bolt shared a photo with his beloved to his Instagram before the Olympics, captioning it ‘President and First Lady’.
Her following rapidly increased after the news broke about Bolt’s night of passion with Duarte.
At the time, Kasi compared Bolt’s behaviour to ‘shopping at Primark’ – the UK discount retailer.
And hit back again by ‘liking’ a picture on Instagram that said: “When your girl is Selfridges, and you cheat on her with Primark.”
Kasi then liked another tweet directed at boyfriend Bolt which said: “You traded your life with a goddess for a one night fling with someone who will never even come close.”
Jamaican superstar Bolt whisked Jady from Rio nightclub All In after swapping sexy messages using Google Translate.
