"Hysterical, crazy, bold, fearless, humble, kind, adorable...all synonyms for Tim Conway," Lawrence wrote on Instagram. "I am so lucky to ever have shared a stage with him. Harvey and Tim are together again. The angels are laughing out loud tonight." Lawrence joined other celebrities, including Tom Bergeron, Neil Patrick Harris and SpongeBob SquarePants in paying tribute to Conway, who died today at age 85.
