Beyoncé
The 'Crazy in Love' hitmaker headlined the world famous festival in 2011.
Her husband, Jay-Z, headlined three years before her.
She was the first solo black woman to top the bill on the Pyramid Stage, and became the first solo female artist to headline the festival since Sinéad O'Connor in 1990.
Despite being met with criticism by some who considered her "too pop" for Glasto, her set was one for the history books and met with wide acclaim.
