Mark Wahlberg and Sean "Diddy" Combs are the latest celebrities to flock to the aid of Flint, Michigan, where residents are in the throes of an emergency caused by lead-tainted drinking water.
The actor and music mogul announced they will send a million bottles of water to the Detroit suburb from AQUAhydrate, the Los Angeles-based water company they each co-own.
Wahlberg and Diddy are now among a slew of celebs who've pitched in to help quench Flint's thirst after officials switched from Detroit's municipal system and began instead drawing from the tainted Flint River as a cost-saving measure.
On Friday, rock band Pearl Jam announced it would be donating $300,000 to the United Way's Flint Water Fund, Rolling Stone reports.
One of the earliest celebrities to pitch into the effort, Cher sent nearly 200,000 bottles of water to the city on Wednesday after tweeting her outrage for days and pleading with fellow celebrities to help.

"Maybe fellow artists will help Flint in any way they choose," Cher tweeted Jan. 16, before calling people in showbiz "notoriously generous."
And it appears the singer and actress hit the nail on the head as a steady stream of well-knowns continue to step up to help Flint.
On Sunday, late night host Jimmy Fallon tweeted that he'd be donating $10,000 to the Community Foundation of Greater Flint. "How about 10 friends match me?" he wrote.
Among the celebrities who've also pledged support are Emenim, Wiz Khalifa and Big Sean.
"I am devastated by the water crisis that has put the entire city of Flint in a state of emergency," Big Sean, who grew up in nearby Detroit, said in a statement.
Flint's lead problem dates back as far as 2014 when the city began drawing water from the Flint River without adding a chemical to control corrosion.
The result was that lead from outdated pipes leached into the drinking water for a year and a half and caused a huge spike in child lead poisoning in the city.
While the city has now switched back to the Detroit water supply, officials fear the damage done to the city's aging pipes may be irreversible.
