The Mickey Mouse Club's most famous original mouseketeer, Annette Funicello, died on April 8 from complications of multiple sclerosis. She was 70. The actress first experienced symptoms of the disease during the filming of Back to the Beach, where she reunited with longtime co-star Frankie Avalon in 1987. Funicello's family told Extra that the actress had spent years in a MS coma. They took her off life support and were by her side when she passed away.
