Beyonce, Bill Clinton hang out at the Made in America festival

It wasn't politics as usual this weekend for Bill Clinton.

The former president and husband of Democratic presidential nominee Hillary Clinton mixed it up Sunday with music stars at the Budweiser Made in America Festival in Philadelphia.

The two-day music celebration featured artists including Rihanna, Coldplay and Chance the Rapper. In the crowd, festival founder Jay Z chilled with Beyoncé, who turned 35 on Sunday.
