It’s nice to have a superstar friend.

Taylor Swift tops PEOPLE’s 2023 Most Intriguing People of the Year list, and in this week’s cover story, the Grammy winner’s friends, collaborators and tour openers share what she’s like offstage and out of the spotlight.

Swift known the rock act Haim — composed of sisters Este, 37, Danielle, 34, and Alana Haim, 31, who collaborated with her on “No Body, No Crime” in 2020 — for nearly a decade.

“She’s incredibly prolific,” says Danielle. “Every time we all get together, we get so excited because we know she’s going to play us something new and groundbreaking. Her heart is always open, and you can hear it in her songs.”

And despite her breakneck schedule, Swift always shows up.

“She has always put her friends before herself in every situation,” Alana says. “She’s the kind of friend that checks up on us for weeks after a tough breakup and is a shoulder to lean on.”

Indeed, Swift met her longtime friend Hayley Williams, frontwoman of Paramore, when they were both up for the best new artist Grammy in 2008.

Swift has worked closely with music producer Aaron Dessner, 47, since collaborating on her pandemic projects Folklore and Evermore, who says, “She’s legitimately just a very down to earth and hardworking person” in the time that he’s known her.

“She is an absolute genius,” Dessner adds, “and thankfully also a truly wonderful human being.”
