@pagesix: 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. 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. 📸: Getty; Annie Wermiel
