Usain Bolt and his fiancée, Kasi Bennett, have welcomed twins into their family. The Olympic champion announced the babies' arrival on Instagram with a heartwarming snapshot of the family of five. "You are the rock of this family and the best father to our children." "We adore you forever and ever!" he wrote in the post dated August 5. Bolt and Bennett were engaged in April 2017 and became parents for the first time last year. The sprint king has two other children, a son named Tai and a daughter named Coretta. Bolt made history when he became the first person to run 100 meters in under 10 seconds three times at a single Olympics - 9.79 seconds - winning gold medals for Jamaica at both Beijing 2008 and London 2012. His career scoring margin over fellow sprinter Justin Gatlin is largest in all sports - 1,519-1,408 (33 races). He also holds the world record for the most consecutive 100 meter heats wins with 19 straight victories from Beijing through Rio de Janeiro 2016. No one else has won more than seven straight events. Bolt's wife, Kasi Bennett, is a former basketball player who attended Columbia University. She was drafted by the WNBA's New York Liberty but never played pro ball. In 2015, she filed for divorce after just 18 months of marriage citing irreconcilable differences.
