Sunsets, shellfish, and plenty of tequila. That's how the Jonas Brothers chose to celebrate out East this Labor Day Weekend. On Sunday, longtime friends and collaborators Nick Jonas and John Varvatos hosted the ultimate end-of-summer bash at Montauk hot spot, The Crow's Nest, in honor of their latest collab: Villa One ultra-premium tequila. Despite the non-fashion-related nature of the launch, it was certainly a stylish affair.

Nick's wife Priyanka Chopra, was of course on hand to support, as were his brothers, Joe and Kevin. They were among a slew of A-list attendees, including Kelly Bensimon, Steve Madden, Chris Cuomo, and hairstylist to the stars, Sally Hershberger, who enjoyed a dreamy al fresco dinner (featuring a shellfish feast), hand-rolled cigars, beachside bonfires, and sips of the new Villa One varietals.
