If you’ve spent more than five minutes on TikTok lately, you’ve probably seen Alix Earle getting ready for a night out. But look past the makeup brushes and hair extensions, and you’ll notice a revolving door of family members.
Actually, it’s a lot of them.
Most people know Alix as the "Internet's Big Sister," but in real life, she’s the eldest of five. The family dynamic is famously messy—her podcast is literally called Hot Mess—but it’s also weirdly aspirational. People are obsessed with how she managed to turn a scandalous divorce and a headline-making stepmom into a tight-knit "modern family" that walks runway shows together.
The Full Breakdown of Alix Earle Siblings
Alix isn't an only child. Far from it. She has one full sister, Ashtin Earle, and three half-siblings from her father’s second marriage: Izabel, Penelope, and Thomas James II.
The age gaps are pretty wild. Alix was born in December 2000, making her 25 years old now. Her youngest brother, Thomas, is only 8. It’s a range that covers everything from "post-grad life in NYC" to "second-grade playground drama."
Ashtin Earle: The "Cool" Sister
Ashtin is the sibling you see most. Born on April 7, 2003, she’s Alix’s only full sister. They share the same parents, TJ and Alisa Earle.
For a long time, Ashtin was just the "mysterious brunette" in the background of Alix’s videos. Now? She’s a massive influencer in her own right with millions of followers. People love her because she’s the total opposite of Alix. Where Alix is high-energy and chaotic, Ashtin is chill, dry, and—as Alix puts it—just "cool."

She recently finished up at Tulane University and moved to New York City. If you follow the tabloids, you probably saw her linked to DJ John Summit over the summer of 2024, though they’ve since called it quits.
Izabel Earle: The Bridge
Izabel (born November 2012) is the eldest of the half-siblings. Her birth was actually a huge turning point for the family.
Before Izabel arrived, things were... tense. TJ Earle’s marriage to Ashley Dupré (the woman at the center of the 2008 Eliot Spitzer scandal) didn't exactly go over well with the older girls at first. Alix and Ashtin have admitted they were "not the best" to their stepmother in the beginning. Think pranks involving toothpaste in shoes and chocolate-covered garlic.
But when Izabel was born, Alix felt an "overwhelming feeling" of protection. That baby basically forced the family to grow up and get along. Alix even dedicated a dance to Izabel during her stint on Dancing with the Stars in late 2025.
Penelope and Thomas James II
Then you have the "littles."
- Penelope Earle: Born in September 2014. She’s currently 11 and a competitive horseback rider. Alix says Penelope is the most like her in terms of personality—blunt, honest, and high energy.
- Thomas James Earle II: The "baby" of the group. Born in April 2017, he’s the only boy. He makes occasional cameos, usually being pampered by his four older sisters.
Why the Earle Family Dynamic Actually Works
You’d think a family born out of a massive cheating scandal would be fractured. Instead, they’re usually all in the same room. Alix’s mom, Alisa, even hangs out with TJ and Ashley.

It wasn't always like this.
Alix recently opened up on her podcast about the "years of fighting" it took to get here. It wasn't an overnight "blended family" success story. They had to hash it out. The key, according to Alix, was when she stopped looking at the past and started looking at her younger siblings.
It’s a lesson in maturity that most 20-somethings don't have to navigate in front of 10 million people.
Real Examples of the Siblings in the Spotlight
If you need proof of how close they are, look at Miami Swim Week 2024.
Alix made her Sports Illustrated Swimsuit runway debut, but she didn’t do it alone. She brought Ashtin, Izabel, and Penelope out with her. The older two wore black-and-white bikinis while the younger girls wore bright pink and red one-pieces.
They also do a "sibling gift exchange" every Christmas that basically breaks the TikTok algorithm. On Christmas 2025, Alix posted a video of the younger kids waking her and Ashtin up at 6:30 a.m. to open presents. It’s remarkably normal for a family that lives in a literal castle in New Jersey.

What Most People Get Wrong About the Alix Earle Siblings
The biggest misconception is that they’re all full siblings.
Because they look so much alike—especially the girls—fans often assume they all have the same mom. They don't. But the fact that people can't tell the difference is a testament to how well they’ve blended.
Another mistake? Thinking they’re all trying to be influencers. While Ashtin has definitely followed in Alix’s footsteps, the younger three are just kids. Alix has been pretty protective about how much of their "real" lives she shows, even though they’re happy to jump in a "Get Ready With Me" video once in a while.
