The first acts on the line-up were revealed earlier this week, with Sia, David Guetta, Bastille, Jess Glynne, Years & Years, Sigma Jake Bugg, Foxes and Rita Ora among those confirmed to play so far.
Tickets will be up for grabs from 9.30am, with festival-goers choosing between two sites: Hylands Park in Chelmsford or Weston Park in Staffordshire. V festival runs from 21-22 August.
Rihanna’s headline set will be her “only UK festival of the summer” according to organisers, ruling her out of Glastonbury, while Bieber will be making his debut at the chart-friendly event.
Tickets cost £189 plus booking fee for a weekend with camping, or £165 plus booking fee for a weekend without camping. Day tickets are also available for £89 plus booking fee.

Got sweaty palms already? Check out our handy tips for dealing with the demand:
1) Make sure you are ready and waiting with the web page up at least five minutes before 9.30am.
2) Do not let your computer, phone or whatever device holds the key to your happiness run out of battery.
3) Register your details with the website you are booking from in advance, if you can, but don’t panic if you haven’t left enough time as your tickets will be held while you fill out your information.
4) Check how many tickets you are allowed to buy in one purchase. If you try to buy more than the limited number, your booking may be cancelled without notice, meaning no-one gets to go.
5) Get your friends to try too, but stay in contact in case you all succeed and end up with a bunch of tickets you didn’t want. If you do need to sell any on, do so at face value. No-one likes a tout.
6) Be patient and avoid refreshing or switching between browsers. Stick with one tab and have some faith! Be prepared to wait for an hour to get tickets.
