Beyonce Knowles blew the crowd away at the Glastonbury festival this weekend in England -- where she sang a cover of Kings of Leon's "Sex on Fire."

Wearing nothing more than a black leotard and a very shot gold sequined jacket, Knowles killed it while husband Jay-Z and Gwyneth Paltrow watched the show together in the audience.

During the show, Bey told the crowd "I want you all to know right now you are witnessing my dream, I always wanted to be a rock star and tonight we are all rock stars."
