Usain Bolt Engaged to Model Kasi Bennett During Birthday Celebration
Post Malone Engaged to Christy Lee One Year After Debuting Romance
Usain Bolt is running towards his happily ever after.
After all, the eight-time Olympic gold medalist proposed to his longtime girlfriend Kasi Bennett after more than a decade of dating as they celebrated his 40th birthday, Bennett shared on social media.
"So many sleepless nights planning UB's 40th with Kasi…little did she know we were secretly planning the surprise of a lifetime," the couple's friend Nikolette Williams wrote on Instagram Aug. 22, which Bennett shared on her Instagram Story. "You both deserve all the happiness in the world. UB's heart is literally gold, and Kasi the absolutely sweetest!"
The model, donning a sparkling form-fitting gown for the occasion, showed off her oval-cut diamond ring in another Instagram Story.
Ahead of the proposal, Bennett—who shares kids Olympia, 6, and 5-year-old twins Thunder and Saint with Bolt—honored her longtime love for his 40th birthday with a sweet tribute.
"My love, my home, my forever," she captioned the Aug. 21 Instagram post. "You are an incredible dad and truly the center of our little world. Your legacy is extraordinary, but the man behind it will always be what makes me proudest. So grateful to do this fun life we've created with you."
While Bennett—who began dating the fastest man in history in 2013—has continued cheering him on, Bolt proved he's her biggest fan, too. Indeed, he couldn't help but put a spotlight on the influencer for her 36th birthday.
"Happy birthday to the most wonderful woman in the world great partner and even better mother," he wrote on Instagram in July. "I know that the future only holds happiness and prosperity for you. You are a God-blessed woman and I am happy to be in your life happy birthday again."

When it comes to their golden romance, Bolt previously revealed that his prime example would be none other than his parents Wellesley Bolt and Jennifer Bolt.
"I want to be like that, I want to have what my parents have," he told People in 2016. "I want to take my time to make sure everything is perfect."
"She's happy, I'm happy," Bolt added. "For me, over the years, I’ve waited because I want to make sure it's the right person."
While Bolt and Bennett wait to cross that finish line together, keep reading for more celebrity engagements.
