The British event, held on two sites in Chelmsford and Staffordshire, revealed the first acts gracing its line-up on Monday morning with more still to be announced.
Ri-Ri and Biebs will top the bill, playing alongside the likes of Sia, David Guetta, Bastille, Kaiser Chiefs, Faithless, Jess Glynne, Jake Bugg, Little Mix, Years & Years, Tinie Tempah, Rita Ora, Sigma, John Newman, Fleur East, Foxes and Lethal Bizzle.
Craig David’s TS5 will be making an appearance, as will Soul II Soul, James Morrison, Travis, Katy B, Example and the newly reunited All Saints.
Festival organisers have promised that Rihanna’s slot will be her “only UK festival of the summer” which, if true, will rule her out for Glastonbury. The “Work” singer last played V Festival five years ago, while Bieber will be making his debut during his Purpose world tour.
