British YouTubers Dan Howell and Phil Lester are packing their bags again, after announcing an 80-date live tour that will visit 18 countries in 2018.

Dubbed the 'Interactive Introverts' world tour, it follows the pair's debut 'The Amazing Tour Is Not On Fire' series of concerts, which visited six countries in 2016.

This time round, Dan and Phil will kick off in Brighton at the end of April, spend a month in the UK before travelling to Ireland, the Netherlands, Russia, Germany, Poland, Finland, Sweden, a month and a half of dates in the US, Canada, Australia, New Zealand and the Philippines.

Further dates yet to be nailed down are promised for Brazil, Mexico, Hong Kong, Singapore and India, with the tour due to finish in September 2018.

Fans are being promised "two internet dwelling, insecure nerds standing under the spotlight to give the people what they want: an epic interactive experience of rants, roasts, battles, stories and surprises that will make you laugh, cry, cringe and puts the audience in control unlike anything before".

Tickets will go on sale for the annnounced dates on 14 November at 4pm local time in the various countries. Expect a surge in browser tab-refreshing, and joyful social-media posts from fans who manage to bag tickets.
