Thesp played Cha Cha in 'Grease'

Annette Charles, who played Cha Cha DiGregorio in the 1978 film version of “Grease,” died Wednesday night in Los Angeles from complications with cancer. She was 63 and received the diagnosis only in recent months.

In “Grease” Charles’ Cha Cha did a sexy dance with John Travolta’s Danny Zuko at the nationally broadcast school dance contest, prompting Olivia Newton-John’s Sandy to leave in a fit of jealousy.

The actress guested on a variety of TV series during the 1970s including “The Flying Nun,” “Mod Squad” and “The Bionic Woman.”

She appeared in Haskell Wexler’s 1985 film “Latino” and in a 1987 episode of “Magnum, P.I.”

Charles appeared in a 2002 episode of VH1′s “Where Are They Now?” series.
