Watch Hilary Duff Dance To 'Crazy In Love' At Beyoncé's Formation World Tour

The 'Sparks' singer loves a good concert

Lizzie McGuire once fangirled over Aaron Carter, but in real life, Hilary Duff is drinking Beyoncé's Lemonade. And she's not the only former Disney star getting in "Formation" -- Demi Lovato is, too. On Saturday night (May 14), the two singers attended Bey's insane "Formation" world tour at Pasadena's Rose Bowl.

DJ Khaled opened the show alongside special guests Snoop Dogg, Fat Joe, and Big Sean. Then Beyoncé went all out for her two-hour performance, which included a Prince tribute and a ***flawless*** dance to Desiigner's "Panda."

Ashton Kutcher, Mila Kunis, Bradley Cooper, Khloé and Kourtney Kardashian, Kerry Washington, and pretty much everyone ever also watched Beyoncé slay this weekend. We assume our invite got lost in the mail?
