Hamptons parties Courtesy Harbour MontaukOne of the hottest party’s on July 4th was publicist Kelly Brady’s birthday bash.

Memorial Day Weekend may be the kickoff to Hamptons season, the time when New Yorkers flee the city and run wild on Long Island’s South Fork, but July 4th is when the East End party circuit really starts to grind.

From an upper crust art fête to a PR maven’s yacht party, here’s an inside look at the Hamptons Fourth of July parties that made waves this weekend.

The most fashionable party of the long weekend was definitely the Revolve kickoff at this gorgeous house in Sagaponack.

All the cool girls were there, including model/'Gone Girl' star Emily Ratajkowski and girl about town/DJ Leigh Lezark.

British DJ Chelsea Leyland made friends with the camera -- and the gigantic chess board.

Guests sipped crisp summer cocktails made with DeLéon Tequila.

We're guessing more than a few people loaded their Revolve pistols with tequila.

In Bridgehampton, the crowd at Hamptons magazine's ArtHamptons brunch was no less fashionable but slightly more vintage.

Former 'Real Housewives of New York' star Aviva Drescher was among the guests toasting Assouline's new book, 'Dinner with Jackson Pollock: Recipes, Art & Nature.'

Vie Vite rosé flowed and guests noshed on brunch bites that were made using the famed drip painter's recipes.

Theatre power couple Stewart F. Lane and Bonnie Comley celebrated the birth of our nation with a red, white, and blue photo shoot on the beach...

...as did their children, Franky, Lenny, and...

...Leah.

At Harbour restaurant in Montauk, E! News correspondent Alicia Quarles hosted a birthday bash for Brandsway Creative PR maven Kelly Brady.

The celebration took place on and off a boat docked at Harbour, with a guest list that included model Jessica Hart and former 'Celebrity Apprentice' star Aubrey O'Day.

Reggae band Twister performed a sunset set at Navy Beach in Montauk on Sunday. Navy Beach is the ultimate chill spot for beach-loving Hamptonites. It's co-owned by New York restaurateur Silvano Marchetto's daughter, Leyla.

On July 4th, fireworks could be seen from the shore at Navy Beach.
