Rihanna and Justin Bieber to Headline V Festival

Get ready for Rihanna and Justin Bieber. The two megastars are joining forces to co-headline the U.K.’s V Festival in August, but they’re not the only ones on the bill.

Big Sean, Rita Ora, Sia, David Guetta, Little Mix, and Halsey are also on the star-studded roster for the 21st annual festival, which has been headlined by Beyoncé, Justin Timberlake, and Calvin Harris in the past.

V Festival is slated to take place at two venues (Hylands Park and Staffordshire) over two dates (Aug. 20-21). While many names have been confirmed, organizers promise that even more acts will be announced.

V is also special because it will reportedly be RiRi and Biebs’ only U.K. showings this summer.

Before they head overseas, Bieber will launch his “Purpose World Tour” on March 9 in Seattle, while the “Work” singer kicks off her “ANTI World Tour” on March 12 in Jacksonville, Fla.

Tickets for V Festival are set to go on sale Friday (Feb. 26).
