According to reports surfacing online today, Metallica, Prince and Outkast are to soon be announced as performers at this June’s Glastonbury Festival.

A festival insider close to music site Gigwise has seemingly confirmed that all three mega-acts have been booked for the event, and it’s only a matter of time when official confirmations are announced.

The site’s source says “I was hearing that Metallica will be headlining Glastonbury – I don’t know when it gets released, but I heard that today,”, continuing “Prince and Outkast are going to be playing Glastonbury, with Outkast apparently playing underneath Prince.”

If confirmed, the three acts will join the already-announced Arcade Fire, Lily Allen, Gorgon City and Stanton Warriors.
