Singer-songwriter Lesley Gore died Monday of lung cancer at New York University Langone Medical Center in Manhattan, her partner of 33 years Lois Sasson told the Associated Press. She was 68.

Gore is best-known for hits like “It’s My Party,” “Judy’s Turn To Cry,” “Sunshine, Lollipops, And Rainbows” and the feminist anthem “You Don’t Own Me”-- among many others.

"She was a wonderful human being -- caring, giving, a great feminist, great woman, great human being, great humanitarian," Sasson, who designs jewelry, told the AP.

Gore was only 16 when her first hit single “It’s My Party,” which was produced by Quincy Jones, was released. "We recorded [it] on a Saturday afternoon, March 30, and I heard the record for the first time on April 6. I was driving to school, literally seven days later ... so when it started getting played, we weren't prepared for it. We didn't even know it had been released,” she said during an interview with After Ellen in 2005.

Though Gore went on to continue with music and create new tunes, she always sang her fans’ favorites. “When I get up on stage I do ‘It’s My Party,’ I do ‘Sunshine Lollipops,’ I do all the songs people expect me to do, and then hopefully I give them a little something extra,” she told the news site.

The former '60s teen idol came out to the public after her fame had passed. She turned “You Don’t Own Me” into public service announcement about reproductive rights during the 2012 presidential campaign, the AP said. She realized she was a lesbian while she was at college at Sarah Lawrence.

Her partner, brother and mother survive her.
