Sebastian Korda’s post-match interview was going smoothly—until a verbal slip turned it into a viral moment. While congratulating him on his win over Flavio Cobolli, emcee Michelle Yu accidentally said he had “sex” instead of “success” against the Italian.
Watching the interview on television, Nelly Korda recorded the moment as it happened. Her reaction was instant laughter, which escalated when her brother delivered a perfectly timed deadpan response. Asked about the secret behind his success against Cobolli, Sebastian replied, “Well, he’s a good-looking guy,” without missing a beat. Nelly burst out laughing.
She later shared the clip on her Instagram Story, her laughter clearly audible, along with laughing and crying emojis and the caption “Dead.”
The viral moment came during a dominant run by Sebastian, who reached his 10th ATP Tour final with a 76-minute performance featuring 12 aces and no break points faced.
The Korda siblings are known for their playful support. When Sebastian reached an ATP final in 2025, Nelly skipped a formal congratulatory post and instead poked fun at the poor image quality of his celebration photo.
Their support also shows up in more meaningful ways. Sebastian once drove over an hour to watch the final holes of Nelly’s win at the Annika Driven by Gainbridge at Pelican in November 2024—the first time he had ever seen her win live. He later praised her resilience and work ethic.
Sebastian also caddied for Nelly at the PNC Championship in 2021, and the siblings regularly text each other through matches despite competing across different time zones.
Nelly has openly called Sebastian the most gifted athlete in the family, highlighting his exceptional hand-eye coordination—high praise coming from a 16-time LPGA Tour winner.
Superstitions also play a role in their relationship. Nelly avoids watching Sebastian’s matches live when he is ahead, believing it could jinx him. She even looks away during key points.
Their sister Jessica reacts differently. Calm while watching golf, she becomes visibly animated during Sebastian’s tennis matches, often cheering loudly from the couch.
When Sebastian won the Mubadala Citi DC Open in 2024, both sisters posted reactions simultaneously—each in their own uncoordinated but supportive style.
Sebastian has often spoken about what that support means to him, calling both sisters his biggest inspirations and crediting their work ethic and achievements for motivating his own career.
Sebastian is set to play the Delray Beach final on Sunday. A victory would earn him his third ATP title. Jessica will be watching closely, and Nelly may tune in—if her superstitions allow.
