Celebrities including Beyoncé, George Clooney, and Jamie Foxx will take part in a benefit concert to raise funds for victims of Hurricane Harvey next week.
The one-hour telethon will be broadcast live in the US on 12 September at 20:00 ET (15:00 BST).
Hand in Hand: A Benefit for Hurricane Harvey Relief will also be streamed live on Facebook, Twitter, and YouTube.
Hurricane Harvey brought devastating floods and displaced thousands of people when it hit Texas on 25 August.
The state’s governor, Greg Abbott, has said the bill for reconstruction could be as high as $180bn (£138bn).
Various celebrities announced their involvement in the fundraiser on Twitter:
Proceeds from the concert will go to various charities including the United Way of Greater Houston, Save the Children, and the Mayor’s Fund for Hurricane Harvey Relief.
Viewers will be able to donate by phone, text message and online from the start of the programme until one hour after it has finished.
On Tuesday night’s episode of The Tonight Show, host Jimmy Fallon also announced the show will be donating $1m (£762k) to the Hurricane Harvey relief fund set up by Houston Texans star JJ Watts.
The fund has raised over $20m (£15.3m) so far.
