Brooks Nader dated both Carlos Alcaraz, Jannik Sinner during US Open

Wasn’t this the plot of the Zendaya movie “Challengers”?

Sports Illustrated Swimsuit model Brooks Nader was romantically playing doubles with both men’s finalists at the 2025 US Open, a source tells us.

The reality honey deuce was dating both the tennis tournament’s No. 1 and 2 seeds — archrivals Carlos Alcaraz and Jannik Sinner — at the time of the tournament, a source tells Page Six.

Call it the opposite of a double fault!

Nader’s tennis romance buzz was first served up on SiriusXM’s Page Six Radio late last month when the star of the new Hulu reality show, “Love Thy Nader,” and her sisters revealed the Sports Illustrated alum was playing the field (or the court?) with “a little roster” of suitors.

Grace Ann Nader said her older sister was seeing men from “every field and court” — but “not the NBA” kind.

Grace Ann then dropped another clue about her sister’s beau, telling us his name “rhymes with winner.” (Meaning Italian star Sinner!)

The chatty sibling quipped, “There are many players in the game,” before Brooks, 28, told her, “Stop talking! I’m going to punch you when we get home already.”

After the Page Six Radio exclusive, late-night host Jimmy Kimmel asked Brooks flat out if she was dating Sinner, to which she replied, “Is this, like, an interrogation? I’m so scared right now,” before adding, “You’re close… you’re warm.”

Then on Wednesday, Grace Ann threw us a curveball when she told to E! her sister was actually romancing 24-year-old Sinner’s biggest competitor.

“Dating is such a loose term, but I do know he’s the man of the hour,” Grace Ann revealed.

Brooks had been sitting front row when Alcaraz, 22, played Arthur Rinderknech at the Open on Aug. 31. The Spanish athlete then went on to beat Sinner in the finals on Sept. 7.

Reps for Nader did not comment, and reps for Alcaraz and Sinner did not immediately get back to us.

Brooks was last linked to “Dancing With the Stars” hoofer Gleb Savchenko — but they split in April after a steamy on-again, off-again eight-month romance.

She was previously married to real estate investor Billy Haire, but they split in 2024 and their divorce was finalized a year later.

Nader also casually dated former NFL quarterback Tom Brady, whom she connected with at Michael Rubin’s annual Fourth of July white party in 2024.

Alcaraz, for his part, was seen celebrating his US Open win with friends, family and models at hot private club Chez Margeaux on Sunday.
