Usain Bolt showed off his infant twins in a lovely Father's Day shot. In the announcement, the Jamaican great disclosed for the first time the names of his new twin kids, Saint Leo Bolt and Thunder Bolt, which he and fiancée Kasi Bennett named. He said they were chosen after saints and angels. Bolt also shared a photo of himself holding his babies for the first time. "My life changed in an instant when I held my twins for the first time," he wrote on Instagram. "I love them more than anything in this world and would do anything for them." He added that they're healthy and doing well under the weight of such big names. "They weigh over 9 pounds each!" he exclaimed. The Olympic champion also thanked his family and friends for their support during this special time in his life. Bol was engaged to Bennett last year and they're set to marry in July 2019 in Jamaica. The 31-year-old athlete announced the news back in January 2018 after two years of dating. At the time, he told People that he chose Bennett because she made him feel young again. "When you find someone who makes you feel young again, knows how to have fun, is easy going, and doesn't mind being around your family, then they are perfect for you," he said.
