Sunday marked the 35th birthday of human angel Beyoncé Knowles [1]. To celebrate, the pop star attended Budweiser's Made in America Festival in Philadelphia. At one point, she chatted with former president and potential first gentleman Bill Clinton; at another, Chance the Rapper sang her a sweet birthday song from the stage while she bashfully hid behind Jay Z. Beyoncé of course deserved a little downtime on such a holy day. After all, she's been killing it on the Formation World Tour [2] for months now, and she just recently shut down the MTV VMAs with a showstopping 15-minute performance [3]. For the record, in light of all her professional prowess, it's amazing to see that the "Happy Birthday" song can make her shy.
