Liam Payne has broken the news that a charity festival for children's cancer has been cancelled.
The One Direction star was due to play at the event in aid of Children With Cancer UK. But Payne said the London event had been cancelled due to bad weather.
He said in a video message: "Tonight's SummerChime fest has been cancelled due to a weather warning.
"I am so sorry for everyone who was excited to see the show.
"Hopefully I get to see you all again some day."
The event was cancelled for safety reasons with heavy rain and strong winds forecast.
All Saints and Louisa were also due to play at SummerChime.
This decision was not taken lightly and was made following weather warnings forecasting heavy rain and gusts of wind, which can be dangerous at outdoor events.
