She died Wednesday night, said her agent, Derek Maki. Her death comes a little more than two months after the death of "Grease" actor Jeff Conaway, whose character Kenickie was Cha Cha's date at the school dance. Oozing a sultry confidence on film, Charles introduced her character at the dance by saying, "They call me Cha Cha, 'cause I'm the best dancer at St. Bernadette's." "... with the worst reputation!" responded Frenchie, played by actress Didie Conn. Charles also appeared on many television shows during the 1970s and early 1980s, including "Barnaby Jones," "The Bionic Woman," "Magnum, P.I.," ''Bonanza," ''The Mod Squad," ''Gunsmoke" and "The Flying Nun."
She later became a speech professor under her birth name, Annette Cardona, at California State University, Northridge.
