Beyoncé and Jay Z just might be the queen and king of Coachella! One week after Beyoncé stole the spotlight during a surprise duet with her sister, Solange, the husband and wife returned to the music festival this weekend, partying it up with pals Usher and Nas before and after Jay Z’s performance with Pharrell. It was also a family affair, as the couple spent time with the Knowles family matriarch, Tina, and danced with Solange’s son, Daniel Julez Smith.
