Bey came out in "Formation" with a performance of the hit song, dressed in a black-and-white polka dot pantsuit and accompanied by a team of backup dancers dressed in blue pantsuits -- notice a theme here? -- wearing "I'm With Her" T-shirts.
"I want my daughter to grow up seeing a woman lead our country and know that her possibilities are limitless," the GRAMMY winner told the crowd.
"There was a time when a woman's opinion did not matter… less than 100 years ago, women did not have the right to vote. Look how far we've come from having no voice to being on the brink of history by electing the first woman president," Bey said. "But we have to vote. The world looks to us as a progressive country that needs change."
The Democratic nominee herself took the stage at the end of Bey's performance to thank the singer for her support. "I want to thank Beyoncé for standing up and showing the world we are strongest when we look out for each other," she said.
Clinton also took to Instagram to share an adorable snap of herself with Beyoncé and Jay Z from before the big show, which saw performances by both Mr. and Mrs. Carter.
"Beyoncé & Jay Z & Hillary & You?," the pic's caption read.
