LOS ANGELES (CNN) -- Annette Funicello, one of the best-known members of the original 1950s "Mickey Mouse Club" and a star of numerous 1960s "beach party" films, died Monday at a California hospital, the Walt Disney Co. said.
Funicello, who was 70, "died peacefully from complications due to multiple sclerosis, a disease she battled for over 25 years," the Disney statement said.
"We are so sorry to lose Mother," her three children said in a statement. "She is no longer suffering anymore and is now dancing in heaven. We love and will miss her terribly."
Funicello was just 13 when she was selected by Walt Disney himself to be one of the original Mouseketeers of the "Mickey Mouse Club," the 1950s television variety show aimed at children.
Funicello, who had a background in dance, quickly became one of the most popular Mouseketeers.
She "was and always will be a cherished member of the Disney family, synonymous with the word Mouseketeer, and a true Disney Legend," Disney chairman and CEO Bob Iger said.
She remained with Disney after leaving the "Mickey Mouse Club," appearing in TV shows including "Zorro" (1957), "The Nine Lives of Elfego Baca" (1958) and starring in the Disney feature films "The Shaggy Dog" (1959), "Babes in Toyland" (1961), "The Misadventures of Merlin Jones" (1964) and "The Monkey's Uncle" (1965).
The most enduring images of Funicello, though, may be of her in a bikini, her primary wardrobe when she co-starred with teen idol Frankie Avalon in beach party movies in the early 1960s. These included "Beach Party" (1963), "Muscle Beach Party" (1964), "Bikini Beach" (1964), "Beach Blanket Bingo" (1965), and "How to Stuff a Wild Bikini" (1965).
The movies helped sell her music. Funicello had Top-40 hits including "Tall Paul," "First Name Initial," "How Will I Know My Love," and "Pineapple Princess." Along with the singles, she recorded several successful albums, including "Hawaiiannette" (1960), "Italiannette" (1960) and "Dance Annette" (1961).
"She will forever hold a place in our hearts as one of Walt Disney's brightest stars, delighting an entire generation of baby boomers with her jubilant personality and endless talent," Iger said in a statement released Monday. "Annette was well-known for being as beautiful inside as she was on the outside, and she faced her physical challenges with dignity, bravery and grace. All of us at Disney join with family, friends, and fans around the world in celebrating her extraordinary life.
Funicello moved with her family from her birthplace of Utica, New York, to Los Angeles when she was 4.
Walt Disney saw her dancing the lead in "Swan Lake" at the Starlight Bowl in Burbank when she was 13. Disney asked her to audition for a new children's TV series he was developing called "The Mickey Mouse Club." She was hired on the spot to become a Mouseketeer, Disney's statement said.
Annette became the viewers' favorite soon after the show debuted in October 1955. Although only three original seasons were produced, the show continued to be see in reruns for another four decades.
