U2 have reportedly been forced to delay their album and tour due to a due to a scheduling issue.
According to Billboard, the Irish rockers won't be going back into the studio until they can find time to record new material with their producers - Ryan Tedder and Paul Epworth.
A source told the publication: "It seems to be taking longer for them to finish an album as they get older, but the great thing about U2 is that the whole of a record is always better than the sum of its parts."
The insider added: "That magic that the band always seems to capture.... they have yet to capture it."
It was previously suggested that U2's next album was likely to be released in the summer of this year, with a tour to follow shortly after.
