If you’ve spent any time in the corner of the internet where lo-fi indie rock lives, you know Greta Kline. Or rather, you know Frankie Cosmos. She’s the daughter of Hollywood royalty—Kevin Kline and Phoebe Cates—but she’s built a world that feels entirely her own, one small, two-minute song at a time. Because her lyrics are so diaristic and intimate, people feel like they know her. They feel like they’re reading her mail.
Naturally, that leads to a lot of Googling about her personal life. The big question usually topping the search bar is: is Greta Kline married? Let’s just get the short answer out of the way. No, Greta Kline is not married. As of early 2026, there is no public record of a marriage license, no secret wedding photos, and no "husband" mentioned in her liner notes. She’s famously private about the specifics of her current dating life, even if her songs give you the vibe that she’s telling you everything.
The Relationship That Everyone Still Remembers
It’s kinda funny how the internet works. You can break up with someone years ago, but if you’re both musicians, the digital footprint lasts forever. For a long time, Greta Kline’s name was synonymous with Aaron Maine, the frontman of the band Porches.
They were the ultimate New York indie power couple. They lived together in Greenwich Village. They played in each other’s bands—Greta actually played bass for Porches for a while. It was that classic DIY romance where the art and the life are totally tangled up. But that ended years ago. Around 2017 or 2018, they went their separate ways.
Greta has talked openly in interviews, specifically with Stereogum, about how weird it is to have fans still obsessed with that relationship. She mentioned how fans would send her art of the two of them kissing long after they’d split. Honestly, that sounds like a nightmare. Imagine trying to move on while people are tagging you in "relationship goals" posts with your ex.

Why People Keep Asking
There are a few reasons why the marriage rumors keep popping up:
- The Phoebe Cates Connection: Her parents have been married since 1989. In Hollywood years, that’s basically a millennium. People often project that "long-term stability" onto the kids.
- Intimate Lyrics: When you write songs about laundry, dishes, and sleeping next to someone, listeners assume those songs are about a spouse.
- The "Secretive" Vibe: Greta doesn't do the "Instagram influencer" thing. She doesn't post "hard launches" of her partners. In the absence of info, people just guess.
What’s Actually Happening in 2026?
Greta is currently busy with the rollout of the sixth Frankie Cosmos studio album, Different Talking, which dropped in June 2025 via Sub Pop. If you look at the credits for that record, you see the same tight-knit circle. She’s working with Alex Bailey, Katie Von Schleicher, and Hugo Stanley.
While there’s been some speculation among fans on Reddit and Discord about her relationship with her bandmates or other New York musicians, it’s all just "vibes" and hearsay. There is zero evidence of a wedding.
Actually, Greta’s recent work seems more focused on the concept of "community" rather than just one-on-one romance. Different Talking was her first self-produced album, and she’s spent a lot of time talking about the growth of the band as a unit.

The Difference Between Greta Kline and Frankie Cosmos
It’s important to remember that "Frankie Cosmos" started as a stage name—a tribute to Frank O'Hara and her then-boyfriend Aaron Maine—but it’s now the name of a full four-piece band. Greta has been vocal about how she wants people to stop using the names interchangeably.
When you search for her marital status, you’re looking for info on Greta Kline the person. But the person who writes the songs is a version of her that might be processing feelings from three years ago. She’s a "prolific" writer. She has hundreds of songs on Bandcamp. Just because a song released in 2025 sounds like a heartbreak ballad doesn't mean she’s heartbroken right now.
The Takeaway on Greta’s Relationship Status
So, if you’re looking for a wedding date or a husband’s name, you won’t find one. Greta Kline is 31 years old, living her life in New York, and keeping her private life exactly that—private.
If you want to stay updated on what she’s actually doing, skip the gossip sites. They usually just scrape old Wikipedia data anyway. Instead, keep an eye on:

- Sub Pop’s official bulletins: This is where the real news about her tours and professional milestones lives.
- The Frankie Cosmos Bandcamp: She still uses this as a direct line to fans.
- The "Nine Songs" interviews: She often does these deep-dive interviews (like the one with The Line of Best Fit) where she talks about the music that shaped her. It gives way more insight into her head than a paparazzi photo ever could.
Don't expect a marriage announcement anytime soon. She seems perfectly content letting the music speak for her, and the music is saying she's focused on the craft, her band, and the weird, small moments of New York life.
Check the credits on the Different Talking LP if you want to see who she's really spending her time with—it's her musical collaborators, the people who have been the backbone of her sound for the last several years. That’s the most "official" relationship she’s publicizing right now.
Actionable Insights for Fans:
If you want to support Greta's work without speculating on her personal life, the best path is through her DIY roots. Buy her music directly on Bandcamp to ensure the highest percentage of revenue goes to the artist. If you're in New York, keep an eye on smaller venue listings; despite her fame, she still frequents the local indie scene that birthed the "anti-folk" movement she’s so often associated with.
