Celebrities have publicly announced over $10 million in donations to aid relief efforts in the wake of Hurricane Harvey in the past few days, taking to social media to publicize their good deeds and encourage others to pony up.

Sandra Bullock is one of the most recent stars to give money to aid groups in Houston, also making one of the largest individual contributions: $1 million to the Red Cross.

The actress called on people to put their political leanings aside and come together to help those in need.

“There are no politics in eight feet of water,” she said, according to People Magazine. “There are human beings in eight feet of water.”

Kevin Hart jump-started a slew of celebrity donations with his “Harvey Challenge.” The comedian posted an Instagram video two days ago pledging $25,000, in which he called upon his famous friends, including Beyoncé, Jerry Seinfeld and Chris Rock, to match his 25k donation to the Red Cross.

Many celebrities accepted Hart’s challenge, and others followed in their footsteps.

Beyoncé, a Houston native, released a statement to The Houston Chronicle on Monday regarding her aid work (the size of her donation has yet to be specified):

“My heart goes out to my hometown, Houston, and I remain in constant prayer for those affected and for the rescuers who have been so brave and determined to do so much to help,” she said. “I am working closely with my team at BeyGOOD as well as my pastor (Rudy Rasmus at St. John’s in downtown Houston) to implement a plan to help as many as we can.”
