Steve Martin wrote: "I could not be more stunned by the loss of Robin Williams, mensch, great talent, acting partner, genuine soul." Miley Cyrus seemed very distraught by the news. She tweeted: " I can't take the Robin Williams news. I've never cried over someone I've never met but I can't stop."
Even president Barack Obama paid tribute to the actor. On his official Twitter account, the president's message read: "Robin Williams was an airman, a doctor, a genie, a nanny ... and everything in between. But he was one of a kind."
May his soul rest in peace.
