In honor of her 39th birthday on Monday (Oct. 21), Kanye West gifted Kim Kardashian $1 million to multiple prison reform charges on behalf of himself and their children.

Kim tweeted about the generous gift, writing, “I got amazing gifts from my whole family and Kanye [gave] me the most amazing bags,” Kim wrote. “But he also donated $1 million to my favorite charities that work so hard on prison reform on my behalf from him and the kids. This makes my heart so happy!”

In the tweet, Kim shared a photo of a “certificate of donation,” which showed that West, along with their children North, Saint, Chicago and Psalm, had donated $1 million to the criminal justice organizations Cut 50, Buried Alive Project, Equal Justice Initiative and Anti-Recidivism Coalition.

Kim has been a passionate and instrumental advocate of prison reform this year and recently revealed that she’s decided to become a lawyer.

“I just felt like I wanted to be able to fight for people who have paid their dues to society,” she told Vogue this April. “I just felt like the system could be so different, and I wanted to fight to fix it, and if I knew more, I could do more.”

“She’s always had it in her,” Kanye said during the Vogue interview. “What is there not to get about her? She’s Kim Kardashian West.”

Over the weekend, Kanye announced that his long-awaited Jesus Is King album will be arriving Friday (Oct. 25). Despite release dates for the project falling flat in the past, Kanye has also announced he’ll be previewing Jesus Is King at the Forum in Los Angeles on Wednesday (Oct. 23). Tickets for the event will be free to the public on a first come, first serve basis and can also be secured with an advance pre-order of the album. If all goes well, Jesus Is King will drop on Friday, along with Kanye’s IMAX accompanying film of the same name.
