Cher slammed Republican presidential nominee Donald Trump at an event for Democratic candidate Hillary Clinton this past weekend, calling him out as a “f—ing idiot.”

“I’m here for a multitude of reasons,” the music legend told the crowd gathered in Provincetown, Massachusetts on Sunday. “I’m here one out of love and one out of fear… I’m so frightened for what’s going to happen to this particular group, this particular community and I know that there are other people and other minorities that are going to be totally screwed as well.”

The long time LGBTQ rights activist attacked Trump and his running mate Mike Pence, for how they’ll handle gay rights if elected to the White House. “I fear for you because I know what they will try to do. They will try to turn back every clock. They will try to take away every one of your rights,” Cher said. “Like they’ve done with women, you know? Women have lost their rights in such unbelievable ways. I feel like, ‘What happened to the ’70s? We already fought this battle.'”

The Oscar-winning actress is a Clinton supporter and friend, and said the candidate will work “every day” to help the country. Cher, however, did not feel Trump would do the same. “He wants the crowds. He wants the adulation. He doesn’t give a sh– about the work,” Cher said of Trump, comparing his speeches to “racist Fun with Dick and Jane” and trashing his campaign motto: “Make America Great Again.”

“He doesn’t mean, either, ‘we want to Make America Great Again,’ he means we want to make America straight and white,” Cher said. “He just says the weirdest sh–. … I just think he’s a f—ing idiot.”

After applause from the crowd, Cher continued, saying she tried to compare Trump with Adolf Hitler or Joseph Stalin, but found a better similarity with Patty McCormack’s killer child character from 1956 horror flick The Bad Seed. “He’s so Patty McCormack: consummate liar, doesn’t care who she hurts, insane; a sociopathic narcissist. I just wish he’d fall off the face of the Earth.”
