Rumours of Jannik Sinner and Laila Hasanovic split grow after birthday post

The birthday post

Danish model Laila Hasanovic turned 26 on Sunday, 8 November, marking the day with dinner with friends in Copenhagen and a photo carousel showing a birthday cake and childhood pictures. Her caption said she felt fortunate and blessed to be where she is, surrounded by the best people. Jannik Sinner, the world number two, does not appear in the pictures, and outlets report he has neither liked nor commented on her posts. Sinner has been sidelined since July by a knee problem, which makes his absence from her celebrations easy to read as a distance between them.

Signs of a split

Speculation has circulated for several weeks, and outlets describe the birthday as the latest hint rather than proof. On Halloween night, 31 October, Hasanovic posted a TikTok clip in which she pretended to take a phone call and repeated a line about a partner seeing another girl, before revealing a vampire transformation and saying that the other girl was her. Many readers took the clip as an allusion to Sinner. On the same day as the birthday, Sinner published a YouTube video with Darren Cahill, his former coach, looking back on years of success together, and Cahill reportedly gave her birthday post a like.

Sources differ on the timing of Sinner's split from Cahill. Fanpage reports that he has just separated from him to work with Magnus Norman, while Mediafax says the parting comes at the end of the season. Mediafax also reports that the two were first seen together in spring 2025 in Copenhagen, and that Sinner publicly thanked Hasanovic after the Vienna final on 26 October 2025.

New-flirt reports

Journalist Gabriele Parpiglia first reported a social-media flirt between Sinner and volleyball player Greta Galassi, with direct messages exchanged while Sinner was still with Hasanovic. Parpiglia now claims Sinner has fallen for Marialuisa Jacobelli, a sports journalist and TV presenter who is reportedly single. According to the reports, the two met at Palazzo Parigi, a hotel in Milan where Sinner was also spotted on the day of the birthday, and a recent photo Jacobelli posted from Monte-Carlo may show the tennis player. Fanpage describes these reports as remaining unconfirmed.

What has not been confirmed

Mediafax notes that neither Sinner nor Hasanovic has officially confirmed a split. Il Messaggero says Sinner has long kept his sporting and private lives apart, and that even during the relationship the couple shared few moments compared with his sporting content. Il Fatto Quotidiano says the rumours have been circulating for several months, but no statement from either side has settled them.

What comes next

Reports say Sinner is expected at an event at the Allianz tower in Milan on Tuesday, 10 November, where he could speak about his career, physical condition or private life. Il Messaggero adds that he may also talk about his new coach, Magnus Norman. Norman, a former world number two from Sweden, joins the technical team in December and will work alongside Simone Vagnozzi.
