The singer-songwriter released her long-awaited second album 'Guts' last week

Teenage heartbreak isn’t just for teenagers — just ask Olivia Rodrigo.

The pop star has made a career turning her personal ups and downs into sing-along anthems that reflect the overwhelming feelings that can bubble up during the final years of adolescence. But she often finds that the relatability factor of her subject matter extends far beyond the Gen Z reach.

“I actually think that I’m really excited by the way that people are getting behind artists that normally would be deemed for young people,” she tells PEOPLE in this week’s issue. “I love interacting with fans who are my age and people who are going through the struggles that I’m going through in real time, but it’s been really fun also to experience those girls’ dads be like, ‘Wow, I remember when I was going through that heartbreak.’”

Rodrigo, 20, finds a certain comfort in knowing her music can be enjoyed by everyone.

“It’s super cool. Especially with ‘Drivers License,’ I remember when that came out, people of all walks of life would just come up to me and be like, ‘I remember exactly where I was when I was experiencing that heartbreak for the first time.’ It’s just such a cool thing to see that we’re all so much more alike than we are different,” she says. “It just makes me feel less alone. I’m just like, ‘Wow, my experiences aren’t really that unique. Everyone has experienced some sort of pain or loss and insecurity.’”

She continues: “I think people are starting to take teenage girl music a little more seriously, which I’m really happy about.”

Rodrigo released her sophomore album Guts last week, the highly anticipated follow-up to her smash 2021 debut album Sour.

Its first single, “Vampire,” topped the Billboard Hot 100 upon its release, and Rodrigo recently sang it at the 2023 MTV VMAs, along with a high-energy performance of “Get Him Back!”

The star — who spent the night before her album release surprising fans in New York City at the Guts Gallery pop-up experience, hosted by Spotify and American Express — also announced a massive world tour set for 2024 in support of the new album.

Produced by Live Nation, The Guts World Tour will kick off its 75-date run on Friday, Feb. 23 in Palm Springs, CA at Acrisure Arena, with shows across North America and Europe, including New York, Miami, Toronto, London, Paris, and many more before wrapping up in Rodrigo's home of Los Angeles with four back-to-back concerts at the Kia Forum from Aug. 13-17.

She’ll be joined on the road by opening acts The Breeders, PinkPantheress, Chappell Roan and Remi Wolf as opening acts throughout the tour.
