Tennis pro Jannik Sinner debuts new relationship after Brooks Nader tryst

Jannik Sinner is back on the court, but he’s officially off the market.

The pro tennis player debuted his relationship with Danish model Laila Hasanovic, despite recent rumblings of a romance between him and Brooks Nader.

“Everyone here, my family, girlfriend, friends, and my whole team also watching at home, thank you so much for your support,” Sinner, 24, said in his speech after winning the Vienna Open on Sunday.

As he said thank you on the court, the camera panned to a smiling Hasanovic, 24, who sat alongside the athlete’s family.

Sinner’s last public relationship was with fellow tennis star Anna Kalinskaya. They debuted their relationship in May 2024, but a year later, he confirmed he was single.

Hasanovic, for her part, reportedly dated Formula 1 driver Mick Schumacher for three years before they broke up in April.

Sinner’s relationship debut comes after Nader, 28, and her sisters hinted that she was dating the four-time Grand Slam winner during their August appearance on “Page Six Radio.”

“I always have good ones,” Brooks confessed of her “roster” of suitors when co-host Evan Real noted that her DMs “must be popping.”

“Every field and court,” her sister Grace Ann exclusively revealed as Brooks’ jaw dropped.

Although the sisters remained coy as the “Dancing With the Stars” alum got visibly annoyed that they were exposing her dating life, Grace Ann continued to spill the tea, noting, “It rhymes with winner.”

Co-host Danny Murphy guessed again, asking whether the person in question was Sinner and her other sister Mary Holland said “No comment,” with a smile as Brooks cursed.

Last month, Grace Ann claimed that Brooks was actually dating Sinner’s rival, Carlos Alcaraz, adding that the 2025 US Open champ had met her other two sisters, Mary Holland and Sarah Jane, and how she was “dying” to as well.

“Dating is such a loose term, but I do know he’s the man of the hour,” she dished just days after Brooks was spotted sitting front row when Alcaraz, 22, played Arthur Rinderknech at the Open on Aug. 31.

In another surprising twist, a source exclusively told Page Six that the Sports Illustrated Swimsuit model was dating the two tennis pros at the same time during the tournament — where they went head to head in the finals.

When confronted about her alleged love triangle, Brooks playfully alluded to the rumors being true.

“I would just say, a lady never kisses and tells, especially twice,” she responded on “Watch What Happens Live with Andy Cohen” on Sept.17, seemingly confirming the flings.

The “Love Thy Nader” star previously dated her “DWTS” pro partner, Gleb Savchenko. The pair shared a steamy on-again, off-again relationship before their split in April.

Brooks was also married to advertising exec Billy Haire from 2019 to 2024.
