Bey and Solange were at the Made In America Festival in Philadelphia organised by Bey's very own Mr Jay Z (now in its second year!)Beyonce stormed the stage on day one and was followed by Solange who did the after-party set in a jazzy mismatchy shirt and skirt - but not before the girls caught up backstage. Best sister act ever.
It's clearly a family thing - because Queen Bey and sister Solange had the crowds in the palm of their hands. The whole time.
As for Jay Z, he left the onstage antics to the girls and kept his cool doing that understated festival thing - shirt round the waist, beer in plastic cup...
Here's a look at more photos of Mrs Carter in action - we just can't get enough.
