Playing on the main stage, the band asked the crowd to throw a Roc-A-Fella diamond sign with their hands so they photograph it for the rapper, who also runs the band’s label.
“We’re taking a picture now for our boss, a guy called Jay-Z,” bassist Pete Wentz told the crowd. “So put your diamonds in the sky right now.”
The NME cover stars also used their festival appearance – which Wentz only arrived for with minutes to spare due to a transport mix-up – to up date fans on their next album, which the band are currently recording.
“We’re in the studio right now and everyone is asking us what we’re doing? ‘Is it going to be emo or pop punk or about dating girls?’,” explained Wentz. “We don’t know what to tell, but we want you to know we still hate everyone else!”
