Jannik Sinner's girlfriend and model Laila Hasanovic regularly hits the gym for a workout. The two have dominated the headlines in recent months for their relationship.
On Sunday, Laila shared a mirror selfie before she jumped inside for an intense workout. She was wearing a black gym outfit with white shoes while holding a sipper in one hand and the smartphone with which she clicked the selfie in the other hand.

The Italian player confirmed her relationship with the model after winning the Vienna Open in October. While he didn't directly name her, he mentioned that his girlfriend was in the stands cheering for him.
"Thank you so much for the support," Sinner told reporters after the win. "The work you put in, the effort. Also, to understand me at times, it is not easy, but thank you for putting in the effort. Everyone here, with family, my girlfriend, friends. To my whole team and also those watching at home. Thank you so much for the support."
The camera caught Laila Hasanovic clapping and cheering Sinner, whose parents, Johann and Siglinde, were also in attendance.
Sinner's girlfriend Laila is a Danish model and influencer. She was previously in a relationship with former Formula 1 driver Mick Schumacher. Before Laila, Sinner possibly dated reality TV star Brooks Nader, since she was spotted at the US Open in August.
