Tennis star Jannik Sinner faces fresh questions regarding his relationship with Danish model Laila Hasanovic, with Italian media and social networks speculating over a potential split, EXPRESS reported.
The 25-year-old Italian player and the 26-year-old Hasanovic officially confirmed their relationship in October 2025, according to T-Online. While Hasanovic was seen supporting Sinner from the stands during his Wimbledon triumph in July, the couple has not been seen together since, as noted by 20 Minuten.
Speculation intensified after Hasanovic celebrated her birthday in Copenhagen over the weekend, sharing numerous photographs with friends on Instagram that excluded Sinner entirely, Heute reported.
“Danke für alle Geburtstagswünsche.”
Earlier around Halloween, followers pointed to a video where Hasanovic dressed as a vampire and sang a line from Kylie Cantrall’s song “The Answer”: “You were right, he has been talking to another girl,” as reported by T-Online.
Amid the separation rumors, Italian media outlets including the television broadcaster Tgcom24 reported that Sinner may already have established contact with another woman, identified as 28-year-old Greta Galassi, EXPRESS stated.
Galassi is a former volleyball player and 2015 Miss World finalist who now works in the fashion industry with roughly 109,000 Instagram followers, according to 20 Minuten. Berichten zufolge sollen sich Sinner und Galassi bereits getroffen haben, wobei diese Angaben bislang nicht bestätigt sind.
Abseits der Spekulationen pausiert Sinner wegen anhaltender Kniebeschwerden und beendete seine Saison im Oktober vorzeitig. In a recent YouTube vlog, the Italian player detailed the physical toll of his rehabilitation.
“Meine Mandeln mussten entfernt werden und ich habe etwas an Gewicht verloren, wie man im Gesicht vielleicht sieht,” Sinner explained in the vlog regarding his recent medical procedures, as cited by 20 Minuten.
