While 'Hair' hitmaker Gaga pushes the boundaries of fashion - having worn a dress made entirely out of meat and appearing onstage wearing a prosthetic pregnant stomach - Chester Bennington, lead singer with the 'Numb' rockers, said his backstage rituals put her to shame.
He joked: "Lady Gaga has got nothing on us. I need an entirely white room where no other human has been. I then bathe in the purest goat's milk for three hours before going on stage."
The band - which also includes guitarists Mike Shinoda and Brad Delson, drummer Rob Bourdon, bassist David Farrell and keyboard player Joe Hahn - are set to headline the Download Festival in the UK this Sunday (12.06.11), and say they are honoured to be playing the huge rock event.
Chester added to the Daily Star newspaper: "Being American we never had many good rock festivals to go to as kids.
"Donington is a place we all dreamed of playing when we were growing up. Now we are headlining, it's awesome.
"We tend to play big outdoor gigs so it won't be too different.
"On this tour we decided to bring all the imagery and visuals of our album 'A Thousand Suns' on the road with us. There's a strong narrative."
