Jennifer Lopez and Ben Affleck Match In White For Pre-Fourth of July Party

Over the weekend, celebrities flocked to the Hamptons for the annual 4th of July party at sports merchandise billionaire Michael Rubin's mansion in Bridgehampton. Amongst the many stars in the crowd of over 350 people were married couple Jennifer Lopez and Ben Affleck, dressed in matching white.

Affleck wore a cream blazer over a white t-shirt and slacks. Lopez had on a flowing summer dress with a cutout below the bust, which was embellished with a little bow. She had her hair up in a sleek ponytail and wore gold hoops and a chain.

Also at the party were stars Jay-Z, Kendall Jenner, Hailey and Justin Bieber, Emily Ratajkowski, Tom Brady, Corey Gamble, and Lori Harvey. There were performances from Usher and Ne-Yo, and the party went on for hours.

The couple enjoyed a day of shopping in Bridgehampton as well, attending the Art Affair with their kids and step-kids, 17-year-old Violet, 11-year-old Samuel, and 15-year-old Emme. J.Lo and Affleck were photographed holding hands.

“They all looked like they had a great time and seemed very cute and sweet together,” a source told ET. “Ben and Jen took some selfies with fans and both of them looked like they were in a great mood."

Affleck was wearing a black button down over a black t-shirt and blue jeans, carrying their bags from the shopping excursion, while Lopez was in a bit more color. Her one-piece khaki culottes were covered in a spring floral pattern and cinched in at her waist with a woven belt. Lopez wore it with pink platformed espadrilles with open toes and had her hair pulled back into a bun. She was also carrying a white purse on a long strap, wearing her gold hoops and a gold bracelet for accessories.
