The king and queen...have arrived.
Beyoncé and Jay-Z made a rare public appearance on Saturday night at Sean "Diddy" Combs' star-studded 50th birthday party at his home in Los Angeles.
Beyoncé dazzled in a strapless black and silver crystal embellished Kujta & Meri gown with leafy detailing and a thigh-high slit, paired with long black gloves, a silver clutch and black sandals. She wore her hair, dyed a dark brown, down in waves. Jay-Z wore a black tux.
The bash was also attended by the likes of Kim Kardashian and husband and rapper Kanye West, her sisters Khloe Kardashian and Kylie Jenner, the latter's ex-boyfriend and rapper Tyga, plus stars such as Leonardo DiCaprio, Kate Beckinsale, Paris Hilton, Ellen Pompeo, Lala Anthony, Janelle Monáe, Cardi B and Offset, Post Malone, Pharrell Williams, Jaden Smith, Fergie, Regina King, Kobe Bryant, Big Sean and ex-turned-friend Jhené Aiko, Usher, Naomi Campbell, French Montana, Lil Kim, 2 Chainz, G-Eazy, Machine Gun Kelly, Snoop Dogg, The Weeknd, Swizz Beatz, Kevin Hart, Nelly and Mary J. Blige.
At the party, Jay and Kanye reunited in public for the first time since 2016, when they famously feuded.
Diddy was also joined by his family—his mother Janice Combs and kids Christian, Justin, Chance, Quincy, and twins D'Lila Star and Jessie James.
"His mom and kids all hung out with him and spent time dancing together," an eyewitness told E! News. "There was a large stage set up and lots of performances. People went crazy when Mary J. Blige got up and performed 'Real Love' with dancers. Everyone danced all night and had a great time. There was also a DJ that spun in between performances by Pharrell and Lil Kim. The night featured great music from the past and present. It was a big dance party with everyone on the floor and focused on the stage."
"They served food from McDonald's, with apple pies and breakfast sandwiches passed around on trays," the eyewitness said. "The party was sponsored by Ciroc Vodka and they had bottles everywhere. There was a CBD station of products for guests to take as they walked around the party."
Diddy received a white birthday cake with the word "LOVE" printed on it.
"The night was all about letting Diddy know much he is loved," the eyewitness said. "He had an amazing night and partied until morning. He seemed so happy to have everyone from all different walks of life there along side of him to celebrate this new decade."
