The singer has taken to Twitter.com to warn fans against paying the inflated prices for dodgy tickets and he is pointing them to the Twickets app for last-minute On The Road Again show seats.

In a message on the social media site, he writes, "Outrageous that tickets for our UK shows are trading at hundreds (of British pounds) on some sites. Please don't use them!"

He continues, "Instead we've made plenty of extra great seats available on the Twickets app for every night at face value prices."
