Lynch was rushed to a California hospital on Saturday with a heart condition and later died, his manager said, reported TMZ online.
Lynch's manager, Johnny Fratto, announced the 'Wack Pack' member's death on Twitter.
"I am so sorry and so sad to inform everyone that my friend Eric "The Actor" Lynch passed away yesterday afternoon," Fratto wrote.
Lynch, whose height was listed as 3 feet 5 inches and who used a motorised wheelchair, called into the Stern show just last week to announce that his parents were going to be his caretakers going forward.
