When it comes to Beyonce AND Solange Knowles - we'd give ANYTHING to be part of the sisterhood. No really. Could they be more fabulous?
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.
