Meanwhile, Years & Years are planning to release a new album this year.
The 'Eyes Shut' hitmakers were keen to take a break from their globe-trotting careers last September and buried themselves in the studio to pen tracks for their second LP.
Asked when fans can expect a follow-up to their 2015 debut 'Communion', frontman Olly, 26, said at the time: "Around September we'll take a break and start work on the album."
Olly had already started thinking about potential collaborators and said he was desperate to get Rihanna on board for their next release.
Speaking to BANG Showbiz, he said: "We've started thinking about it [the next album]. We've got ideas. I want to do a song with Rihanna we need to make that work."
Tickets are on sale now from £30 and available via Mighty Hoopla's website.
