Tennis power couple Alex de Minaur and Katie Boulter melted fans’ hearts with a touching Instagram post celebrating Boulter’s 29th birthday on August 1, 2025. De Minaur, the world No. 8 Australian, shared a story featuring Boulter with a teddy bear, a single carnation, and a birthday balloon, captioning it, “Happy birthday to the finest human I know.” The gesture, reported by Times of India, showcased their deep affection, delighting fans who flooded social media with praise. One X user, @TennisFanatic22, wrote, “Alex and Katie are the definition of #CoupleGoals! So sweet.”
The couple, engaged since December 23, 2024, after dating since March 2020, met by chance at a hotel, bonding over a 6 a.m. coffee, as Boulter shared with The Age. “From that moment, I knew I was in it for the long haul,” she said. Their relationship, built on mutual support, has seen them cheer each other through career highs and lows. De Minaur famously paused a 2022 Wimbledon press conference to praise Boulter’s win over Karolina Plíšková, saying, “Can we just talk about Katie Boulter today?” Boulter, Britain’s No. 1 at world No. 23, credited De Minaur’s support after her 2024 Wimbledon loss, noting his advice: “One match doesn’t define your career.”
Both enjoyed stellar 2025 seasons, with De Minaur reaching the Wimbledon quarterfinals and winning the 2025 Washington Open, while Boulter secured titles in San Diego and Nottingham. Their engagement announcement, featuring Boulter’s emerald-cut diamond ring, drew congratulations from peers like Emma Raducanu, who commented, “Congrats!!” on Instagram. Despite a potential United Cup clash looming in December 2025, where Australia faces Great Britain, Boulter admitted to Daily Mail she’s “not thrilled” about facing De Minaur but emphasized their mutual support.
The birthday post, simple yet heartfelt, underscores their playful yet profound bond, with Boulter calling De Minaur her “best example of what I want to be” for his selflessness. As they prepare for the Cincinnati Open and US Open, their love story continues to captivate tennis fans worldwide.
