Carlos Alcaraz Celebrates US Open Win With Champagne, After Party With Models

Carlos Alcaraz celebrated his US Open win on Sunday in epic fashion … first, he doused himself in champagne — and then he hit a New York hot spot and partied with models!!

The 22-year-old Spaniard beat Jannik Sinner 6-2, 3-6, 6-1, 6-4 at Arthur Ashe Stadium as President Donald Trump watched from the stands … and before he left the venue, he popped some serious bubbly with his team.

Check out footage from his locker room celly — Alcaraz surprised his pals with a massive container of booze, but they were armed with their own bottles … and it wasn’t long before everyone, and everything, was covered in alcohol.

The post-match bash lasted a bit … and after Alcaraz showered off, he continued the festivities at Chez Margaux in Manhattan, where models Brianna Bardhi and Tika Camaj were enjoying an evening out.

Bardhi actually posed for a pic with the tennis star … as did the supper club’s chef, Jean-Georges Vongerichten.

Alcaraz had a big grin on his face in both photos — showing the glow of his victory hadn’t yet worn off.
