Grammy Awards weekend brought on tons of parties in LA [1], but none of them were quite as star-studded as the Roc Nation and Three Six Zero brunch [2]. On Saturday, Beyoncé hit up the bash with Jay Z and several other stars, including Kim Kardashian [3], Kanye West [4], and Rihanna [5]. While Bey made her grand entrance in a cleavage-baring jumpsuit, Kim opted for a red two-piece outfit that showed off her stomach. The stars let loose while taking in the excitement, with Beyoncé and Jay Z posing for a snap with Willow Smith, and Kim catching up with Rihanna. The most entertaining duo of them all, though, was none other than Jay Z and Kanye. At one point, Jay had a bottle of Rosé Champagne in one hand and a filled glass in another, while Kanye stood on a couch and hung over him.
