Sports billionaire Michael Rubin threw what has been dubbed the “biggest celebrity party ever” with the likes of Leonardo Di Caprio, Beyonce and Kim Kardashian partying away at his 4th of July bash.

Billionaire Michael Rubin threw the “biggest celebrity party” as he celebrated the 4th of July at his $50million mansion in the Hamptons.

The annual bash, when he encourages his famous guests to wear all white, saw the likes of Beyonce and Jay-Z, Leonardo Dicaprio and Kim Kardashian flock to his luxurious home to party the night away, drinking $700 champagne and tequila.

Michael is notably the CEO of Fanatics, the world’s top provider of licensed sports merchandise.

In the video he shared to his Twitter account, fans were given a glimpse inside the iconic party as they were shown clips of Jennifer Lopez and husband Ben Affleck posing for pictures while former The Late Late show host James Corden arrived with friends.

Kevin Hart, DJ Khaled and rappers Lil Baby, Lil Durk and Coi Leray made their way into the function as model Winnie Harlow and Emily Ratajkowski graced guests with their glamorous presence.

Newly weds Hailey and Justin Bieber appeared to be close as they enjoyed the event and sports stars Tom Brady, Kevin Durant and Kylian Mbappe made their most of their day off, partying in Michael’s stunning home.

Beyonce surely caught up with her former Destiny’s Child bandmate, Kelly Rowland, who was also in attendance.

Meanwhile, Lori Harvey and her famous pals, Kendall Jenner, LaLa Anthony, Hailey and Kim showed off their white outfits for Lori’s 686k TikTok followers as they strut their stuff for the camera.

Kim opted for a white knitted crop top and matching skirt but she must have been absolutely mortified when her ex-husband’s ex-girlfriend Chaney wore the exact same outfit.

Fans couldn’t believe the mishap as they posted pictures on Reddit with the caption: “Kanye’s Exes Chaney and Kim attending the same party in the same outfit.”

They were convinced that Chaney was “outshining” Kim and one commented: “Kim must be dying knowing that her ex-husband’s ex-girlfriend is outshining her. Her kryptonite is not getting any attention!”

As well as A-List company, guests were treated to performances from Travis Scott, Jack Harlow and social media start Druski, who each took turns taking over the DJ booth.

Back in June, Michael told Page Six that he was “bringing in some of NYC’s hottest restaurants,” including celebrity favourite pizza spot Lucali and Cucina Alba.

There were no tickets sold for the private event, despite fans desperately trying to get into the function.

A medical and security crew were hired to keep Michael’s celebrity entourage safe throughout the night and by the time the party had come to an end, the team of security shepherded the stars to their expensive and safely guarded cars which were parked on Dune Road.
