Singer and songwriter Lesley Gore, famous for her song "It's My Party," died of lung cancer at a Manhattan hospital yesterday.

Brooklyn-born Gore, 68, released her famous hit at just age 17 in 1963.

"She was a wonderful human being -- caring, giving, a great feminist, great woman, great human being, great humanitarian," her partner of 33 years, Lois Sasson, told The Associated Press.

Gore was discovered by producer Quincy Jones and went on to record other hits, including "You Don't Own Me" and "That's the Way Boys Are."

She was nominated for an Oscar in 1981, with her brother, Michael, for Best Original Song for "Out Here on My Own" in the movie "Fame."

Gore attended Sarah Lawrence College where she studied literature and drama, according to IMDB.com.
