Beyoncé and Jay Z made their way to Vanity Fair's post-Oscars bash on Sunday, making a brief appearance on the red carpet before mingling with Hollywood's hottest stars. Beyoncé wore a floor-length white dress, and inside, she linked up with everyone from her sister, Solange, to Jennifer Lopez [1] to Jared Leto [2] and Lupita Nyong'o. Earlier in the night, she sweetly posted a picture [3] of Solange's Oscars outfit, writing, "Gorgeous," and during the party, she posed with Lupita's brother for an Instagram snap. Lupita wrote, "Just introduced my brother to @beyonce. What are sisters for?!"
