Over the weekend, festival goers from all over gathered at Pilton's Worthy Farm in Somerset, England, for four days of music mania at the 2011 Glastonbury Festival. Not only does the annual festival play host to some of today's biggest names in classic and indie rock, but the bill also boasted some huge pop headliners, like Beyonce and Coldplay. Up-and-coming pop singer and UK native Jessie J also graced the stage over the weekend.

Beyonce's Glastonbury performance was truly ground-breaking in the sense that she is the first woman to ever headline the festival. During her time on stage, which was filled with light shows, dance routines, sparkly costumes and lots of big hair, Beyonce performed songs off of her new album '4' and some of her classic hits (in addition to some covers like Kings of Leon's 'Sex on Fire').

Coldplay also took the stage on June 25, performing for fans during what looked a spectacular stage display of lazers, confetti, and colors. Jessie J also sang at the festival, going against her doctor's orders because she has a fractured leg. She sat in a burgundy throne, cast and all, as she sang hits like 'Price Tag' (recruiting help from a young festival attendee named Shay) and 'Do It Like a Dude.'
