Jamie Foxx will co-host a telethon to raise money for the Hurricane Harvey relief fund.
The 49-year-old actor has confirmed he has donated $25,000 to the cause after the tropical storm ripped through parts of Texas killing more than 30 people and destroying around 50,000 homes, and on September 12 he will be part of the TV event to help generate more money.
He said in an Instagram video: "Just wanted to let everyone in Texas know that we got you. From a fellow Texan, my heart goes out, my prayers go out.
"I've given $25,000 to GlobalGiving.
"Also, September 12, we have a telethon that we're doing. We'll give you more details, so we can raise as much money as we can for everybody down there.
"Houston, everybody, all of those different places. We're here for you. God bless."
US rapper Bun B - who is from Houston, one of the many cities affected by the natural disaster - has revealed the telethon will take place in three cities, Los Angeles, New York and Nashville.
Scooter Braun, who produced Ariana Grande's recent One Love tribute concert in Manchester, is behind this latest event, and Jamie is expected to co-host the LA segment, potentially alongside Hilary Duff.
Bun told gossip website TMZ that Reese Witherspoon and Blake Shelton are in line to host from Nashville, and Michael Strahan - who was born in Houston - will co-present from New York, plus bosses are trying to get fellow Houston-born Kelly Rowland on board to co-host.
The Big Bang Theory's Jim Parsons is also thought to be part of the event.
This comes after a host of stars donated money, including Leonardo DiCaprio and Sandra Bullock, who have both pledged $1 million to help those affected by the tropical storm.
What's more, Miley Cyrus has donated $500,000 to the cause.
Speaking on 'The Ellen Show', she said: "I'm really happy to help in whatever way I can."
Ellen Degeneres has also pledged $1 million to J.J. Watt's Hurricane Harvey Relief Fund.
