The Danish band are currently number one in the UK charts with their fab single '7 Year' so we're totes thrilled they've been added to the bill for this summer's music festival!
It was announced via the V Twitter today.
According to the Official Charts, the band could stay number one this weekend for a third week in a row, after their performance on Jonathan Ross's show on Saturday boosted sales of the track.
Rihanna and Justin Bieber are this year's major headliners, with other acts confirmed including Rita Ora, Ellie Goudling, Jess Glynne, Little Mix, Sia, Kaiser Chiefs, David Guetta and Bastille.
Not too bad, right? Okay, blooming amazing!
