The "Game of Thrones" alum, 23, looked striking in a gown fit for a Bond girl in an Instagram post she shared Saturday. The black Alexandre Vauthier Couture dress features a thigh-high slit and plunging neckline with an attached gold metal collar. Look familiar? Joe's one-time girlfriend Taylor Swift wore the same gown to Vanity Fair's 2016 Oscars after-party.
Jonas channeled his inner Bond in a white tux with a black bow tie and black slacks. Per the couple's social media posts, guests received "Joe Jonas 30" baseball hats designed to look like the famous 007 logo.
Also in attendance: Joe's siblings and sisters-in law, Nick Jonas, Priyanka Chopra and Kevin and Danielle Jonas.
The party, which took place over the weekend in New York, came as a break for the Jonas Brothers, who kicked off their Happiness Begins tour Aug. 7 in Miami. They performed Thursday night in Washington and Saturday night in Boston.
Turner celebrated Joe's actual birthday Thursday on Instagram, where she wished a "happy 30th to my love and the best thing that's ever happened to me" in a since-expired Instagram Story.
Kevin Jonas also wished his younger brother a happy birthday: "You are the man we love you so much now let's play a show and party!!!!!"
Nick Jonas shared a photo of the two of them, calling Joe his "best friend."
Jonas and Turner officially married May 1 in a low-key, Elvis impersonator-officiated Las Vegas ceremony after the Billboard Music Awards. They threw another ceremony two months later in France – one that was significantly more upscale and brought family, friends and other recognizable stars to celebrate together.
