The retired eight-time Olympic gold medalist, Usain Bolt took to social media to introduce his first child to the world. The greatest sprinter of all time became a father last May. Bolt and his partner, Kasi J. Bennett, even gave the little one a very Greek name: Olympia. Of course, next to the name, he added the "lightning," which was his nickname when he swept the big races on the track, both in the 100m and the 200m. https://www.instagram.com/p/CCWNMuxFp6d/?utm_sourceig_embed To celebrate his partner's birthday, he posted pictures on his Instagram from a photo shoot they did with their daughter, who has beautiful eyes. "I want to wish my gf a happy birthday and To let u know I am happy I get to spend ur special day with u. I want nothing but happiness for u and will continue to doing my best keeping a smile on ur face. Now we have started a new chapter together with our daughter Olympia Lightning Bolt I look forward to what the future will bring for us but be reassured that I will be the ROCK for this family. I Love you and happy 21th birthday ," Bolt wrote in his message on Instagram. Olympia means 'Mountain Of The Gods' in Greek. Although Olympia Bolt is the daughter of a famous athlete, perhaps the most famous Olympia was the one born in 375 BC in Epirus - the mother of Alexander the Great. Usain Bolt is an eight-time Olympic gold medallist, winning the Olympic 100 m and 200 m titles at the 2008, 2012 and 2016 Olympics - the only person to do this at three consecutive Olympic Games. He also won two 4 × 100 relay gold medals.
