Solange & Beyoncé Are DJ Heroes

Solange spun some records for a good cause while DJing A Party: Relief for Haiti Edition benefiting Wyclef Jean’s Yele Haiti organization at The Eldridge in New York City on Tuesday (Jan. 26). Her big sis Beyoncé, brother-in-law Jay-Z, and Michelle Williams showed up to lend their support.

“B and Jay were having a blast,” a partygoer told (via Just Jared). “They were dancing and laughing and really into the music. Beyoncé even got on the mic and sang ‘Sweet Thing’! She and Jay were having a genuine good time.”
