Beyonce helped her husband Jay Z kick off his second annual music festival in Philadelphia, Pennsylvania in superstar style on Saturday night (31Aug13) by closing the show as the headlining act.

The rap mogul launched the Budweiser Made In America event last year (12), and his wife graced the stage in front of 50,000 fans to ensure the first day of this year's festival ended on a high note.

The pop beauty opened the show with her huge hits Single Ladies (Put A Ring On It) and Crazy in Love, before drawing the gig to a close with her ballad Halo.

Deadmau5, 2 Chainz, Emeli Sande, and Haim also performed on Saturday, while Nine Inch Nails will serve as the star attraction on Sunday (01Sep13), alongside fellow acts Calvin Harris, Queens of the Stone Age, Kendrick Lamar, Miguel and MACklemore & Ryan Lewis.
