Jennifer Lopez and husband Ben Affleck were in attendance at sports merchandise billionaire Michael Rubin's annual 4th of July white party.
The bash - which was attended by the like of Kim Kardashian, Kendall Jenner, Hailey Bieber, Tom Brady, Lori Harvey and Kylian Mbappe - was hosted at his sprawling, $50million Bridgehampton pad.
Performances from Usher and Ne-Yo and the finest food and drinks were enjoyed by guests who had been brought in by private helicopter from the city.
JLo was pictured arriving in a white maxi dress with a pleated bottom half and a cut-out just about her navel, showing off her washboard abs as she closely followed Ben and her 17-year-old step-daughter Violet.
Despite the pair looking happy and smiling with one another, a few snaps from the night show Jennifer looking sternly focused as she emerged from her mode transport.
Body language expert Judi James has exclusively told us that Ben has "adopted nonchalance as his go-to body language look," and she also claimed that the duo shared a "look of tension" before entering the party.
"Ben seems to have adopted nonchalance as his go-to body language look, despite being married to one of the world’s most desirable women.
"Jennifer’s almost bridal arrival here in sensational wafting white with an entourage sweeping her in majestically, looks out of kilter with the way Ben throws a backward glance as she emerges from her car, keeping both hands stuffed into his trouser pockets as though kicking his heels while his wife finishes the weekly shop at Aldi," Judi added.
"There is even a slither of power-play in the way that Ben waits for his wife to be led up to join him rather than performing an act of convenience to signal her status by walking out towards her car to receive her. There is an initial look of tension from Jennifer’s body language as she is led up to the driveway, with a stern-looking eye expression and the hint of a frown.
"She is quick to extend her hand to instigate a hand clasp with Ben, suggesting she is keen to register and define them as a couple. Their fingers entwine to show closeness although the hint of tension is still there in the way Jennifer’s thumb is still rigidly cocked rather than relaxed into the clasp," she concluded.
Judi's analysis of the pair comes after reports that Jennifer and Ben's honeymoon period is well and truly over after they were recently seen having a number of seemingly tense exchanges.
