You’ve definitely heard it. That soft, haunting piano melody that usually accompanies a video of someone crying, a nostalgic memory of a lost pet, or a dramatic "POV" about heartbreak. Most people know the chorus by heart, but it’s kinda wild how many people don’t actually know who sang it. Or better yet, why it sounds so genuinely painful.
Little did you know alex and sierra was more than just a promotional single from 2014; it was the sonic blueprint for a relationship that the entire world watched fall apart in slow motion.
It’s easy to forget now, but back in 2013, Alex Kinsey and Sierra Deaton were the absolute darlings of The X Factor USA. They didn't just win; they dominated. They were the first and only group to ever win the American version of the show. People were obsessed with them because they were "couple goals" before that was even a cringey term we used. They met on a beach in Florida back in 2009, and by the time they stood in front of Simon Cowell, they were deeply, visibly in love.
But there’s a darker side to the song that fans are still deconstructing a decade later.
Why Little Did You Know Alex and Sierra Still Hits So Hard
The song wasn't just some generic pop track handed to them by a label. While it was co-written by heavy hitters like Ali Tamposi and Toby Gad, Sierra Deaton actually has a writing credit on it. That matters. It’s a song about the heavy, messy work of trying to forgive someone while you’re still hurting.
If you listen closely to the lyrics, it’s a dialogue. Sierra starts by singing about "breaking while you fall asleep" and being "haunted by memories." Then Alex responds, acknowledging his mistakes and promising to wait.
"I’m ready to forgive you but forgetting is a harder fight."

That line is basically the thesis statement for the entire track. It resonates because it isn't a "happily ever after" song. It’s a "we’re barely hanging on but I’m trying" song.
Ironically, the duo described it at the time as a song about hope. They told interviewers it was about believing in a relationship so much that even a total breakdown in communication wouldn't make you quit. But looking back with 20/20 hindsight? It feels like they were singing their own future.
The X Factor Curse and the $1 Million Contract
Winning a reality show is usually the beginning of the end. Alex and Sierra walked away with a $1 million recording contract with Sony Music, which sounds like a dream. In reality, it was a massive weight. Their debut album, It’s About Us, hit number 8 on the Billboard 200, which is actually a pretty solid start. But the industry changed fast.
They were dropped by their label just a year later.
In a very honest Reddit AMA from years ago, they talked about how "their people" would talk to "the label's people" and everything got lost in translation. They were essentially two kids from Florida caught in a corporate machine that didn't know how to market a folk-pop duo once the TV cameras stopped rolling.
What Actually Happened Between Alex and Sierra?
For years, fans wondered if they were still together. They kept posting videos, they toured independently, and they seemed fine. Then, on September 1, 2017, they dropped the bombshell.

They hadn't just broken up. They had been broken up for over a year while still performing as a duo.
Think about that for a second. Every time they sang little did you know alex and sierra on stage in 2016 and early 2017, they were looking at their ex. They were singing lyrics about waiting and loving someone "until the sun dies" while their own romantic sun had already set.
They admitted that the last album and tour were "hard on our hearts." No kidding. They tried to do the "Fleetwood Mac" thing where you keep the band together despite the breakup, but it eventually became too much. They stopped making music together entirely to focus on solo careers.
Where are they now?
If you’re wondering what happened to them after the split, they’ve both stayed in the music world, just in very different lanes.
- Sierra Deaton: She’s arguably had the most public "second act." She’s been in a long-term relationship with Luke Hemmings from 5 Seconds of Summer for years. She’s also a successful songwriter in her own right and has released solo music under the name Essy. She actually co-wrote several songs for 5SOS and Luke’s solo projects.
- Alex Kinsey: He’s been consistently putting out music, too. He formed a band called BoTalks and later released an EP called Party of One. He’s still got that husky, soulful voice that won over Simon Cowell, but he leans a bit more into the indie-rock side of things now.
The TikTok Resurrection
Why did a 2014 song suddenly become a viral titan? It’s the "Sad Girl Autumn" effect. The song has a specific frequency of vulnerability that makes it perfect for short-form video.
It’s been used in over a million videos. It’s the go-to sound for "healing journeys."

The genius of the production is the simplicity. It’s mostly just piano and those two voices. In an era of over-produced hyper-pop, the raw, unpolished feeling of the track stands out. It feels like you’re eavesdropping on a private conversation in a bedroom at 3 AM.
Key takeaways for fans and creators
Honestly, the legacy of this song is a bit of a lesson in artistic authenticity. People didn't connect with it because it was a "hit." They connected because the pain in Sierra’s voice was real.
If you're a creator or a musician looking at why this worked:
- Vulnerability wins: The song admits to "mistakes drowning me." It’s not a flex.
- Simplicity lasts: Trends fade, but a piano and a vocal will always work.
- Context matters: Knowing the singers were actually a couple in crisis adds a layer of "lore" that TikTok loves.
If you want to dive deeper into their discography, don't just stop at the hits. Check out "Bumper Cars" or "Scarecrow." They both capture that same "we're falling apart but I love you" energy.
The story of the song is a reminder that sometimes the best art comes from the things we’re too afraid to say out loud to each other, so we sing them instead.
To really appreciate the song today, listen to the live "unplugged" versions on YouTube. You can see the way they look at each other—or sometimes, the way they avoid looking at each other. It puts the lyrics into a completely different perspective. You can find their full debut album on Spotify or Apple Music under It's About Us.
