PICTURE: Jannik Sinner's rumored girlfriend Laila Hasanovic makes 1st appearance with Italian's parents while showing her support at Vienna Open

Jannik Sinner's rumored girlfriend Laila Hasanovic was spotted supporting the World No. 2 during his opening match at the Vienna Open on Wednesday. Hasanovic was joined by the Italian's parents, father Hanspeter and mother Siglinde, with the trio enjoying the former World No. 1's win against Daniel Altmaier in the Austrian capital.

Sinner, who defended his title at the Six Kings Slam exhibition event before arriving in Vienna, was exceptional on both serve and return, with the 6-0, 6-2 score an accurate reflection of his dominance on the day.

Not long after the conclusion of the contest, a picture surfaced on X, showing Hasanovic, a Danish model and influencer, smiling alongside the Italian's parents.

This isn't the first time that Hasanovic has attended a tennis match featuring the former No. 1. The Dane was present at the French Open, Wimbledon and US Open earlier this year. During his run to the final in New York, the lock screen on Sinner's phone appeared to have a picture of Hasanovic.

Both of them have been tight-lipped about the nature of their relationship.

Jannik Sinner, who won the Vienna Open in 2023 after defeating Daniil Medvedev in the final, spoke about the presence of his parents during his first-round victory over Daniel Altmaier.

"My mom usually gets nervous watching," he said. "I don’t know if she was here in the stands or not. Having my dad in the box, it’s great. Also, my brother is not here. But it’s fine. Maybe he comes to Turin (for the ATP Finals). We are just a very normal family. When I play outside when they are not there watching, my dad is still watching the matches at home. I know he’s watching."

Fellow Italian Flavio Cobolli, 23, awaits Sinner in the second round. This will mark the first time that Sinner and Cobolli face each other in an ATP Tour-level event. The winner will go on to face either Francisco Cerundolo or Alexander Bublik in the quarterfinals.
