Charlie Murphy, Eddie Murphy's brother and a comedian best known for his work on Chappelle's Show, has died after a battle with leukemia, EW has confirmed. He was 57.

Murphy's most popular recurring sketch on Chappelle's Show, which he wrote for and appeared on, was titled "Charlie Murphy's True Hollywood Stories" and featured him recalling real-life encounters with celebrities. This included one with Rick James, where Dave Chappelle's portrayal of the musician repeatedly says "I'm Rick James, b—-!" <iframe src="//" width="512" height="288" frameborder="0" allowfullscreen="" class="" scrolling="no" resize="0" replace_attributes="1" name=""></iframe>

He later worked with his brother on writing the script for 2007's Norbit, which featured him voicing the character of Llyod the dog. More recently, he starred on the Adult Swim series Black Jesus and appeared in the 2016 comedy-horror Meet the Blacks.

Murphy will also be featured on the upcoming season of the Starz drama Power, EW revealed in January. "Starz sends our deepest condolences to Charlie's family and friends," said the network in a statement to EW. "He joined Power for our upcoming season, and his talent shines in every scene. We were fortunate to have worked with him."

Murphy was also part of the ongoing Comedy Get Down Tour with Cedric the Entertainer, Eddie Griffin, D.L. Hughley, and George Lopez. Lopez paid tribute to Murphy in an Instagram posted Wednesday. "I'm heartbroken at the passing of our brother Charlie," he wrote. "In relationships you never want to leave anything unsaid, our conversations before shows and after shows we all told each other and Charlie how we felt! Keep his family in your thoughts and prayers and keep a space for Charlie in [your] heart."

Other comedians and actors, including Chris Rock and Chappelle's Show co-creator Neal Brennan, also honored Murphy with social media posts. See those below.
