Lennon Stella on Channeling Chainsmokers’ & 5SOS’ ‘Energy’ on Arena Tour, Her ‘Experimental’ Debut Album

The singer-songwriter talks to the Pop Shop Podcast about getting “emotionally & physically” over a relationship on her new single “Kissing Other People.”

Last month, Lennon Stella gave her fans a mini-heart attack when she started a tweet with: "also thought you should know I am very pregnant." For those who stopped reading after those nine words ("Yeah, there was a lot people that thought I was actually pregnant," Stella laughed to Billboard in a new interview with the Pop Shop Podcast; listen below), the rest the tweet reads: "…with an album baby and i'm about to pop. … three…two…one here we go 2020."

The 20-year-old singer/songwriter — who has been in the public eye since her 2012 debut on the ABC series Nashville and as part a viral-video duo with her sister in Lennon & Maisy — is finally ready to release her debut album next year and formally introduce herself as an adult solo star. Over the past few months, she's been super busy on the road with The Chainsmokers and 5 Seconds Summer, but once that wraps up, she's focusing entirely on the album.

"Before this tour started, I spent a couple months in LA just diving in and working a bunch on it," she tells Billboard's Pop Shop Podcast. "It's very close to being done, which is very crazy to think about because right now, it feels so scattered in my head. Like, it's kind all over the place. But it's … on its way to being finished. And I'm just really excited to have a full album out in the world, and I think when it's an album … I feel more creative or inspired to be a little more experimental because it just feels like a little bit less pressure on each song."

Stella released her Love, me EP last year, along with some loose songs here and there, but the first taste her debut album is latest single "Kissing Other People," which she co-wrote during a writing camp in Cabo, Mexico, following a breakup.

"So I was dating this guy for a bit and I was kind , we had broken up and I was kind getting in the process moving on and trying to kind get over him and get over just the comfort knowing that he was there," she recalls. "I was talking to Caroline Ailin] about this, who co-]wrote the song, and I was just saying to her how you get to a point when … you can kiss other people and you're like, 'Oh, I didn't feel like I was cheating on you still,' even though we're broken up. Like, I don't feel bad for it anymore, and that's kind when you're like, 'OK, cool, I'm both emotionally and physically over this now.'"

We don't know exactly when Stella's debut album will arrive or its title, but she teases that "it'll be like mid-next year."

In the meantime, she's gifted fans with a few guest spots and features on other artists' songs, including tourmates The Chainsmokers' "Takeaway," also featuring Illenium. While the song's dancey vibe is a far cry from Stella's typical acoustic sound, she likes dipping her toe in other genres. "With features, it's really cool because ultimately, it's not my song," she says. "I can be a part it and I can get in that world and explore that world, but not be committed to it, you know?"

But she has been in that world as part the World War Joy Tour since September, and she'll take what she's soaked up on the road for her very own EU tour, as well as some spot dates in Nashville and Atlanta. "I feel like I've learned a lot just in the sense performing in arenas," she says. "It's obviously totally a different thing. … It's just such a different type performing and a different level energy and obviously production is very different. And everything is just bigger and very alive from start to finish. There's never any dips energy, and I think going from playing in clubs or small theaters to this is so different."

Also on the show, Keith & Katie talk about the best original song nominees at the 2020 Golden Globes, new No. 1s on the Billboard Hot 100 (The Weeknd's "Heartless") and the Billboard 200 (the Frozen II soundtrack), plus the sad news that hip-hop chart-topper Juice WRLD died at age 21 this week.
