Hollywood families are usually a mess of "who is related to who" and the Barker-Kardashian clan is basically the final boss of that game. If you’ve spent any time on TikTok lately, you’ve probably seen Alabama Barker. She’s everywhere. But people get seriously confused about her siblings. Is she an only child? No. Does she have a biological sister? Sorta.
The "Alabama Barker sister" search usually points to one person: Atiana De La Hoya. Honestly, their bond is one of the coolest things about that whole family dynamic. Even though they don't share a dad, you’d never know it by looking at them.
Who Is Atiana De La Hoya?
Basically, Atiana is the "big sister" of the group. She was born in 1999 to Shanna Moakler and boxing legend Oscar De La Hoya. When Travis Barker married Shanna in 2004, he didn't just become a stepdad; he basically raised Atiana as his own.
It’s actually pretty sweet. Even after Travis and Shanna went through their very messy, very public divorce years ago, Travis and Atiana stayed super close. You'll often see her on vacation with the Barkers or hanging out at their Calabasas mansion. She’s an artist and a model, and she’s stayed remarkably low-key compared to some of the other members of the family.
She and Alabama are constantly together. They post "Get Ready With Me" videos and travel the world. If you’re looking for drama between them, you won't find it. They seem to have each other's backs through all the internet hate.

The Kardashian Connection: Enter Penelope Disick
When Travis married Kourtney Kardashian, the family tree basically turned into a forest. Suddenly, Alabama gained a whole new set of siblings. While she has stepbrothers now (Mason and Reign), it’s her relationship with Penelope Disick that people are obsessed with.
Penelope is much younger—born in 2012—but she and Alabama have a really unique bond. It’s that classic "big sister, little sister" vibe. Alabama often features Penelope in her TikToks, doing her makeup or just hanging out. Some critics think it’s "too much" for a young girl to be in that glam environment, but if you actually watch the videos, it just looks like two sisters bonding.
Breaking Down the Siblings
Let’s be real, the math is hard. Here is the actual breakdown of Alabama’s sisters and brothers as of 2026:
- Atiana De La Hoya: Maternal half-sister (same mom, Shanna).
- Landon Barker: Biological brother (the one who's always with Charlie D'Amelio... well, until they broke up).
- Penelope Disick: Stepsister (Kourtney’s daughter).
- Mason and Reign Disick: Stepbrothers.
- Rocky Thirteen Barker: Paternal half-brother (Travis and Kourtney's son born in 2023).
It’s a lot. Honestly, it’s a lot for anyone to keep track of. But for Alabama, it seems to be her normal. She has said in interviews that she loves having a big family. It’s more people to have your back when the internet starts being weird.

Why People Get Confused
The confusion usually stems from Shanna Moakler. Shanna and Alabama have had a very rocky relationship over the years. There were periods where they didn't even speak. Because Atiana is Shanna’s daughter, people often wonder if that causes tension between the two girls.
It doesn't.
Atiana has managed to stay neutral. She stays close to her mom, she stays close to Travis, and she stays close to Alabama. That's a lot of emotional heavy lifting for a 26-year-old. She’s basically the glue.
Then you have the "best friend" factor. Alabama is super close with Jodie Woods (Jordyn Woods' sister). They are together so much that people literally ask if they are related. They aren't. They’re just inseparable.

The Reality of Growing Up "Barker"
Growing up in the spotlight isn't easy. We saw it on Meet the Barkers when Alabama was literally a baby. Now she’s an adult navigating social media. Having sisters like Atiana and even Penelope probably makes it easier. They understand the pressure of the cameras.
The Barker girls are creating their own lane. Alabama is doing the music and influencer thing. Atiana is doing the art thing. They aren't just "Travis Barker’s kids" anymore.
If you’re following the Alabama Barker sister saga, the main thing to remember is that "family" for them isn't about blood. It’s about who showed up. Travis showed up for Atiana, and Kourtney showed up for Alabama.
What You Should Know Now
If you want to keep up with the Barker family dynamic, you really have to look at their social media interactions rather than just news headlines. The headlines focus on the drama between Shanna and Kourtney, but the sisters themselves usually stay out of the mud-slinging.
- Watch the TikToks: Alabama and Penelope's videos give the best insight into their actual daily relationship.
- Follow the Art: Check out Atiana’s custom painting work if you want to see her as an individual rather than just a "sister."
- Ignore the "Estrangement" Rumors: Unless it comes directly from them, the rumors of sisterly beef are almost always fake.
The best way to understand this family is to stop looking for a traditional structure. They are a modern, blended, slightly chaotic, but very loyal group. Alabama may have different types of sisters—half, step, and soul sisters—but to her, they’re just family.
