Curtis and AJ Pritchard have announced they have cancelled their tour due to the ongoing coronavirus outbreak.
The brothers had been due to perform four more gigs on their AJ Live tour, which have now been postponed until further notice.
Fans due to attend the Guildford, Cardiff, Bournemouth and Torquay shows have been told that the dates will be rescheduled when possible.
It comes after Prime Minister Boris Johnson advised the public to stay away from mass gatherings like concerts.
The UK coronavirus death toll yesterday rose to 55 while there have now been 1,543 cases, with more than 7,000 now dead globally.
Taking to their respective Instagrams, Curtis and AJ shared the same message to announce the cancellations as they urged their fans to "stay safe".
They wrote: "This is a message to all of our amazing fans and specifically those who have tickets to our remaining 'AJ Live; Tour Dates.
