Posty is doing the mosty.

Post Malone, 24, is asking his fans to help him donate up to $1 million to a charity of their choosing. The “Circles” singer is using the celebrity fan platform Community to find causes that his fans support.

“Not everyone has the ability to financially support causes that may be close to them or that have helped them in the past,” Malone said in a press release. “The fans are the absolute best and I want to give them the chance to give to charities that mean something to them.”

To tell Malone where they want him to send money, fans can text him directly on his Community phone number: 817-270-6440.

Charities can benefit COVID-19 relief, education, homelessness, hunger, mental health, veterans and more.

This isn’t Malone’s first foray into philanthropy: Earlier this week, he performed a live concert of Nirvana covers on YouTube, which raised over $500,000 for the United Nations Foundation’s COVID-19 Solidarity Response Fund for the World Health Organization, according to CNN. Google matched every dollar donated with $2.

Before the pandemic, Malone was one to toss out big bucks. Videos of him celebrating in Miami during the Super Bowl show Posty dolling out a box full of cash wads on strippers at a club.

On New Year’s Eve, he handed out $100 bills to servers at an after-party in Williamsburg while saying, “My penis thanks you!”
