Gloria Gaynor performed her hit “I Will Survive” at the Angel Ball — hosted by Gabrielle’s Angel Foundation for Cancer Research founded by Denise Rich — and the disco diva told Page Six she feels responsible for a lot of breakups. “I have always said I sang that song for the ladies and the good men,” Gaynor said. “There are a lot of men out there that are not bad — but they just don’t know how to treat a lady. So we end up with these breakups because we need to be treated right.”
