Stella Lefty’s ‘Boston’ Went Hot 100, and She’s Not Picking a Genre Lane Anytime Soon

Stella Lefty didn’t even need a formal Stagecoach slot to feel like one of the weekend’s unavoidable names. Last month at the country festival, the country-pop artist kept popping up across the grounds, joining Cameron Whitcomb and Wyatt Flores onstage while her breakout single “Boston” kept climbing, eventually landing at No. 27 on the Billboard Hot 100 and No. 7 on Hot Country Songs.

“I’m a huge fan of Wyatt and also Cam,” she says. “It’s so crazy to be so embraced in a genre that I’ve always loved. Country music has been such a huge part of my life. And I feel like it’s always scary when you start making music that kind of bleeds into a genre. Country is so specific about who they embrace and how they go about things, so to be accepted in that world is truly the greatest honor.”

At Stagecoach, Lefty linked up with former tourmate Whitcomb for Tyler Childers’ “All Your’n,” and later sang “Boston” during sets from Flores and Diplo. It was another sign of how quickly she’s moved from promising newcomer to someone other artists are clearly happy to pull into the circle.

The Chicago-born singer came up on a home mix that made the whole country-pop conversation feel less like a strategy and more like a natural fact. Taylor Swift and Miley Cyrus were in the mix, but so were Tim McGraw and Brad Paisley, the records her dad played around the house. She wrote for years, then headed to Tulane University to study public health. Music was always there, though, especially once she started posting on TikTok. “I had no plan of doing anything in music,” she says. “I always loved to sing and I was always writing, but I didn’t know anybody that did that.”

After graduating in 2024, she finally started releasing songs in earnest, including “Cynic” and “Grace” in 2025. A signing with Atlantic Outpost earlier this year sped things up further: “Thinking ‘Bout You” and “Slow Dancin’” arrived in January, and then came the song that changed the scale. While on a Nashville songwriting trip a few months ago, she sat at a piano and tossed out a snippet for social media. That clip, which lightly interpolated Noah Kahan’s “Stick Season,” became the backbone of “Boston,” and took off fast. Kahan, unsurprisingly, is credited on the track.

“It was just for fun and I wasn’t thinking anything about it,” Lefty says. “So when people started to like it, I was like, ‘Oh, shoot, I need to finish this.’ I wasn’t thinking about anything so intensely, and that was honestly the most fun part. Building around something that kind of already existed was cool and I’d never done anything like that.”

She followed it with “I Know I Know,” a banjo-led song about trying to get over someone while knowing exactly how quickly a night out can send you back to the same old person. “one glass of wine and you’re on my mind” is the kind of line that lands because it feels familiar, not forced.

“I feel like all of my friends, this is the thing we always talk about,” Lefty says. “You go out and you want to have this night out with your friends, then all of a sudden you start drinking and you start thinking about that one person that haunts you. So, we wrote about it, but in a really lighthearted, fun way.”

Those songs now sit on Is This Heaven?, her six-song EP out Friday, May 15. The project also includes “Something To Lose,” a collaboration with Vincent Mason, whom Lefty is currently dating. “I’m obsessed with this song. It’s one of my favorites that I’ve ever written, and obviously, [he] and I started dating a few months ago,” she says. “I wrote it about being in this place of not wanting to be in a relationship, and then all of a sudden this person comes along and you just have no choice. That’s totally how I felt about him. When we sang it, it just felt so natural and fun. I was like, ‘If I’m going to have any features or collaborate with anybody, it has to be him.’”

Her name, meanwhile, has been stitched into the whole story longer than her recent run might suggest. Stella Lefkofsky is her legal name, but Stella Lefty has always been the version she’s used. “My uncle, my Dad, my brothers, have gone by Lefty… so it was the easiest thing and I didn’t have to change anything,” she says. The family connection also comes with a work ethic she clearly absorbed early. Her father is Groupon co-founder and Tempus AI founder and CEO Eric Lefkofsky, and she describes her household as deeply supportive, but also relentlessly focused.

“My whole family is super hardworking. I think the biggest takeaway is there’s a grit that I feel, like ‘Keep your head down and just keep going…’ I’ve been working as hard as possible and learned that from them. They were super emotionally supportive. They definitely pushed me in that regard and I’m grateful for that.”

She’s heading into a bigger stretch next, opening for Myles Smith and Tucker Wetmore and making her Lollapalooza debut. That, for Lefty, is part of the point: the streaming numbers are one thing, but the room is another.

“I just want to keep playing shows and meeting people, because it’s crazy to see the number on your screen, like, ‘This is how many people are listening.’ But it’s a whole other experience to meet those people and see the people that love the song. So that’s what I’m most looking forward to.”

She’s also already thinking about who she’d like to bring into the mix next. “I’m obsessed with Ella Langley, she’s amazing, so anything with Ella would obviously be a dream. I’m also obsessed with Gracie Abrams, I’m so inspired by her. And I think if Tim McGraw asked me to do something with him, I would die.”

That pull toward both worlds is really the point of Stella Lefty right now. She isn’t trying to tidy it up for anyone. “I’ve been super particular about wanting to live in both spaces as best as I can,” she says. “Every time we’ve been talking about doing something, it’s like, ‘Maybe it would be helpful for the audience if they really understood what lane you wanted to be in,’ and I’m always like, ‘No, I will not pick a lane.’ I won’t, because it wouldn’t be authentic for me. Music now is so genre-bendy and so fluid. I don’t want to put myself into a box because whoever is going to love the music is going to love it.”
