Usain Bolt is now a father-of-three after secretly welcoming twins! Taking to Instagram on Father's Day, the Olympic legend announced the arrival of the two newborns and even shared their unique names with his 10.1 million followers. Alongside a sweet snap of the family of five, Bolt wrote out the names of all his children with a bolt emoji placed after each of them. Up first was the name of his firstborn, whom he welcomed last year in May. The 34-year-old athlete then listed the names of the newest additions to the family: Saint Leo Bolt and Thunder Bolt.

The twins' exact date of birth has been kept under wraps - along with many other details of their arrival. Over on her own account, Bennett posted some additional pictures from the photoshoot, captioning one post: "Happy Father's Day to my forever love! @usainbolt. You are the rock of this family and the greatest daddy to our little ones. We love you world without end!"

However, despite his success, the former Olympian said he would be concerned if his children decided to follow in his footsteps and pursue a career in sports. Speaking to <a href="https://www.thetimes.co.uk/article/7f01bcf2-485f-11ea-9a9d-aed7af30eb98">The Times</a>, he said: "I'm going to say no, initially. If they do, I will support it. But I think the pressure is going to be too much - especially at the level I left it. It's going to be tough to follow. "You have to wait until they get to a certain age to explain to them that people are going to expect a lot from you, because of what I've done in the past. I'll wait until the time is right to explain." <h6>Featured image credit: PCN Photography / Alamy</h6>
