Kanye West is making a big donation in his wife’s name.

In honor of her 39th birthday on Monday, the rapper gifted his wife with designer bags, but that wasn’t all. He also donated a whopping $1 million to charities that focus on prison reform.

“I got amazing gifts from my whole family and Kanye for me the most amazing bags. 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,” tweeted Kim. “This makes my heart so happy!”

Her sister Kourtney also applauded Kanye for his generous donation. “Kanye has the most generous heart, it is inspiring,” she said.

She showed off the certificate announcing that a $1 million donation had been made in her name by Kanye and the couple’s four children—North, Saint, Chicago, and Psalm West—to charities including Cut 50, Buried Alive Project, Equal Justice Initiative, and the Anti-Recidivism Coalition.

Kim has been an advocate for criminal justice reform and has successfully lobbied for the release of prisoners including Alice Marie Johnson prisoners and Momolu Stewart.

It was a big birthday weekend for Mrs. West, who celebrated with friends in Palm Springs and with a dinner hosted by Kanye and her mother Kris Jenner, which was catered by her “favorite Armenian restaurant Carousel.”

On Friday, Kanye will release his long-awaited ninth solo album Jesus Is King along with his IMAX film of the same name. He will premiere both on Wednesday at a special listening and screening at the Forum in Los Angeles.
