Lorde has apologised to fans after postponing her up-coming Australian tour under medical advice.
The singer was due to play eight shows, starting in Melbourne on April 24, but has been told by doctors to return to New Zealand for "immediate rest and recuperation in order to regain complete health and continue touring for the rest of the year," according to a statement from the tour's promoter.
In the announcement, Lorde told fans: "It breaks my heart to have to postpone these shows as the band and I absolutely love playing to Australian crowds, and it was not a decision we made lightly. I know I need to focus on getting better in order to perform at my best. We'll be with you as soon as we can, Aussies".
Organisers are currently trying to reschedule the Australian tour. Lorde is due back in the US for a performance in Baltimore on May 17, before heading to Europe for a series of festival performances.
Her Australian tour had already been expanded, with an extra date added in Sydney after her first show there sold out.
