Rockville Centre-reared Amy Schumer hasn’t forgotten her friends from South Side High School there, the comedy star says.

In an interview accompanying her first Vanity Fair cover, Schumer, 34, says that she’s introduced her coterie of seven old pals to her new friend, Oscar winner Jennifer Lawrence. She added that she spent part of an afternoon last year negotiating with Lawrence’s people to get her friends tickets to the premiere of “The Hunger Games: Mockingjay — Part 2.” “I was like, ‘I have to bring all my friends from high school.’ They were like, ‘Are you serious?’ I was like, ‘Yeah, if I go and don’t bring them, it’ll be an issue.’ ”

In her apartment on Manhattan’s Upper West Side, the “Trainwreck” and “Inside Amy Schumer” star keeps framed photos of her pals, as well as a picture of them on the cover of a throw pillow. “It’s all my friends from high school — these girls, these monsters,” Schumer said. “They’re afraid I’m going to forget about them. So, like, they keep buying me things, to remind me of them.”

Schumer also spoke about New York senator Chuck Schumer, whom Vanity Fair specified is her second cousin once removed, meaning they share the same great-grandparents but not the same grandparents, and are of different generations. The senator — who told the magazine he and Amy’s father played stickball together as youths — phoned her after a mentally ill drifter with a legally purchased semi-automatic pistol killed two people and himself and wounded nine others at a Lafayette, Louisiana, showing of “Trainwreck.”

“I got a call,” she said, “and he was like, ‘Amy, this is your cousin Chuck.’ And I said, ‘I hope this is you asking me to help with guns.’ He laughed. ‘Yeah, that’s what this is.’ I was like, ‘Let’s go. Let’s do it.’ “ The two began a campaign against gun violence, Aiming for Change, and Amy Schumer has filmed a video for the advocacy group Everytown for Gun Safety.

“Every event I go to, you see the same people, and they’re wearing a button of their kid, or kids, or their mother, or someone who died and didn’t have to,” the comedian says. “And they’re like, ‘Thank you. Please keep going.’ Because, unfortunately, someone with some celebrity brings more attention to it than a politician.”
