Ariana Grande has apologised to fans after announcing that three upcoming concerts have had to be rescheduled due to production issues.
The Grammy-winning singer is currently in the midst of her sold-out Eternal Sunshine Tour.
"We are so sorry for these unfortunate scheduling changes," she explained to fans in a statement.
"This was our best and safest option as these challenges with production have come to our attention. The utmost important thing to us all is safety, first and foremost, and also making sure you all see the show as it is intended to run. Thank you so much for your understanding and I cannot wait to see you."
After wrapping up shows in Oakland, Los Angeles and Austin, Grande's team now knows exactly what goes into deconstructing and reconstructing the stage, and has deduced that more time is needed between upcoming dates to ensure it can be built to standard.
New York City's Barclays Centre show on Sunday, 12 July, has been moved to Tuesday, 14 July, to "ensure the full production can be delivered safely and as intended".
Two shows in Boston scheduled for 22 and 24 July will now take place on 23 and 26 July.
Ariana Grande recently broke down in tears on stage during her Los Angeles concert, a week after her split from Ethan Slater was confirmed.
