Rita Moreno (b. Rosita Dolores Alverío, 1931) is an actress arguably known for her roles of aggressive, strong-tempered Latin women who guest starred on The Muppet Show episode 105. On the December 10, 2015 episode of PBS Newshour, she called performing "Fever" with Animal in that episode "one of the funniest things [she's] ever done." She also hosted The Muppets Go Hollywood in 1979.
In 1977, she became the ninth performer to win the Triple Crown of Acting. The first was an Academy Award for Best Supporting Actress in West Side Story (1961), later followed by a Tony for Best Featured Actress in The Ritz (1975) and an Emmy in 1977 for The Muppet Show.
Her Muppet Show Emmy made her the third person to win an Oscar, a Tony, an Emmy, and a Grammy (for the 1972 Electric Company cast album).
For Sesame Street, Moreno provided vocals for two songs -- "Women Can Be" and "There's a Hole in the Bucket." She also appeared on the show in Episode 0637 as her character Millie from The Electric Company.
