Jannik Sinner’s shocking French Open defeat makes girlfriend Laila Hasanovic’s recent video impossible to ignore now

Jannik Sinner’s stunning second-round loss at the 2026 French Open did more than end a 30-match winning streak. It reopened a conversation that has quietly followed the world No. 1 for months. On Thursday morning at Roland-Garros, Argentina’s Juan Manuel Cerundolo pulled off the biggest upset of the tournament so far, beating the top seed in brutal Paris heat that once again exposed Sinner’s physical limits. The defeat also shifted attention toward Sinner’s off-court circle, including girlfriend Laila Hasanovic, whose recent TikTok post suddenly feels oddly timed after the collapse.To casual fans, this looked impossible. Sinner entered Paris as the clear favorite after dominating the tour through the first half of the season. With Carlos Alcaraz sidelined by a wrist injury, the draw appeared to open perfectly for the Italian star. Instead, the tournament changed course before the third round even began.Inside the sport, though, there had already been quiet concern around the conditions. Paris has been dealing with unusually high temperatures this week, and Sinner’s struggles in extreme heat are well known among players and analysts. Tournament organizers appeared aware of it too. His placement in the opening match on Court Philippe-Chatrier raised eyebrows because top-ranked players rarely receive that slot unless there is a scheduling concern behind the scenes.Even with the earlier start, the heat became a factor. Sinner dealt with visible cramping during stretches of the match, and Cerundolo sensed the opening immediately. The Argentine stayed patient, extended rallies, and forced Sinner into uncomfortable movement patterns that slowly broke down his rhythm.ID@undefined Caption not available.ID@undefined Caption not available.What made the upset feel heavier was how quickly the atmosphere around the tournament shifted afterward. Novak Djokovic, Alexander Zverev, and Ben Shelton suddenly moved from outsiders to realistic title threats within a few hours.At the same time, social media began circulating a recent TikTok video from Hasanovic that now carries a different tone after the defeat. In the clip posted on May 25, Hasanovic enters the frame and says, "f*** you" to the camera before a friend jokingly apologizes for her behavior. Hasanovic then returns with, "No we're not!"The video was originally part of a trending joke format, but online reactions changed after Sinner’s exit. Hasanovic was not in Paris for the match and is currently in Copenhagen, yet her post became part of the wider conversation surrounding the upset.Sinner now faces a different challenge than simply recovering from one loss. The defeat has revived questions about whether his physical durability can hold up across two demanding weeks at Grand Slam level, especially in difficult weather. That discussion is no longer theoretical after Paris.
