On Twitter, celebrity friends and fans were talking about the comedian's death, with writer and producer Luke Barnett tweeting, "Very sad to hear about the passing of my buddy Fuquan Johnson. Smiliest, happiest dude, and a local icon in the North Hollywood community, RIP." As The Sun reports, comedians Kevin Hart and Marlon Wayans also took to their Instagram to pay tribute to Johnson.

"Damn... I don't know what to say. RIP Comedian Fuquan Johnson and really hope that my friend @KateQFunny pulls thru," a fan tweeted, while someone else said, "RIP Fuquan Johnson and really praying for a full recovery for Kate Quigley. Stand up is such a small community and every loss hurts. Please be careful out there everyone. Look out for each other."
