Charlie Murphy's death today at 57 from leukemia was a terrible surprise.

His family thought he was getting better, the cast and crew of his current show Power didn't even know he was sick, and he had been active on Twitter as of last night.

Comedians, rapper and other celebrities jumped on social media today to pay tribute to a very funny man.

Wow....This is crazy. All I can say is RIP. Thank you for not only being a friend but for believing in me when I was young in this comedy game. Charlie Murphy did the rewrite for the first movie that I ever did called "Paper Soldiers"....His stories were legendary & unbelievable & heartfelt. I'm lucky to have know you and I'm even luckier to be able to say that I was a friend. You will be missed man. #RIPCharlieMurphy

Today we lost a #RealOne. @therealcharliemurphy was a bad man and funny af. He was honest and straight shooter, no BS kinda dude, awesome Father and family man. Had a gregarious laugh that would make you laugh, he stood on his own 2 feet as a man and as a comic even in the shadows of the brother of one of the greatest to have ever done it. Listening to Charlie tell stories of his life was truly one of my greatest past times. It's why I love this pic. Touring with him these past few years on the #ComedyGetDown was indeed an honor. Though I am sadden by your passing. I pray for all of your loved ones his children and that his soul Rest In Peace. Love you brother C.T.E
