On Thursday, Britain’s 18-year-old Emma Raducanu defeated Greece’s Maria Sakkari at the US Open women’s semi-final, becoming the youngest Grand Slam finalist since an 18-year-old Maria Sharapova made it into the Wimbledon finals in 2004, per The Guardian. On Friday, she took a moment to celebrate ahead of her finals match on Saturday (where she faced off against Canadian Leylah Fernandez and won) by posting a snap of herself practically jumping for joy at the Arthur Ashe Stadium. “Pure happiness under the lights in New York,” she captioned the Instagram post, which gave way to over 13 thousands comments, including one from a very special well-wisher.
Kate Middleton briefly broke from tradition to make a personal social media comment (her first ever!) in which she congratulated Raducanu and wished her luck. “What an incredible achievement Emma! We will all be rooting for you tomorrow,” she wrote, per Harper’s Bazaar. Adding a fingers crossed emoji, she continued, “Wishing you the best of luck!” She then made it extra clear that the message was coming directly from her by signing off with a “C” for Catherine.
Middleton also tweeted the message — and it wasn’t her last! Following the young Brit’s win, she took to @dukeandduchessofcambridge to give a “huge congratulations” to Raducanu for her “stunning performances and historic Grand Slam victory!” Adding, “We are all so proud of you,” she also congratulated Fernandez on her “amazing achievements,” concluding, “It’s been a pleasure to watch. C.”
