Meet Alix Earle's 4 Siblings: All About Her Younger Sisters and Brother

Alix Earle’s siblings, Ashtin, Izabel, Penelope and Thomas, are featured across her social media

Alix Earle is a loving big sister to her four younger siblings.

The TikTok star was born to Thomas (TJ) and Alisa Earle on Dec. 16, 2000, and was soon followed by her younger sister Ashtin on April 7, 2003. Alix’s father split from Alisa when the girls were in elementary school and married Ashley Dupré. Together, TJ and Ashley welcomed Alix’s three youngest siblings: Izabel, Penelope and Thomas James Earle II.

Despite a once-hectic family dynamic, Alix is thankful for the support she’s received from both sides of her family.

“We definitely have a very modern family,” she told ELLE in an August 2023 profile. “Whatever’s happened in the past, we’ve all gotten past it as a family.”

With only a little over two years between Alix and Ashtin, the sisters often show off their close relationship on social media. In April 2024, when Ashtin turned 21, Alix celebrated the special occasion with a big party in New York City.

“I can finally take my sister out with me now!! #21 🎂,” she captioned a series of pictures on Instagram.

From Ashtin’s social media presence to which sister Alix is most like, here's everything to know about Alix Earle’s three sisters and brother.

Alix and her siblings grew up in New Jersey

Alix’s younger sister, Ashtin, shares the same mother and father as her. Raised in Monmouth County, N.J., Alix and Ashtin grew up along the northern part of the Jersey Shore, enjoying summers on the beach.

TJ and Ashley went on to have three children together and still live in New Jersey. Izabel was born on Nov. 10, 2012, followed by Penelope two years later on Sept. 18, 2014. Thomas is the youngest in the family, with TJ and Ashley welcoming him in April 2017.

Ashtin attends Tulane University

While Alix graduated from the University of Miami, Ashtin went to college a bit further from home at Tulane University in New Orleans. Like her sister, Ashtin gives her TikTok followers a peek into her life as a student.

At Tulane, Ashtin is an active member of the Kappa Kappa Gamma sorority, frequently posting content about her sorority and college life on Instagram. Aside from her social life, Ashtin is studying psychology and is part of Tulane’s Service-dog Training and Education Program (TUSTEP), per her LinkedIn.

“Happy finals week,” she wrote in the caption of a May 2024 TikTok video. “(Stop inviting me to things that you know i can’t attend) #finalsweek.”

Ashtin is also an influencer

Alongside her sister, Ashtin has also fostered an online presence on TikTok and Instagram. With over 400,000 followers, much of her content is similar to Alix’s, including “Get Ready With Me” makeup videos and “Day In My Life” vlogs.

She also occasionally posts videos with Alix, like the sisters' trip to the Florida Keys for Mother's Day in 2024, and spotlights her life as a student at Tulane.

Alix incorporates her siblings into her content

Ashtin isn't the only Earle sibling to be featured in Alix's content.

In an August 2023 video on Alix’s TikTok, her two younger sisters, Izabel and Penelope, helped style her to attend the fair. She explained that her little sisters were helping her pick an outfit because “they have better fashion sense than I do,” to which they replied, “We do!”

In April 2024, Alix took part in a trend that highlighted how much her younger sister had grown up. The TikTok video featured pictures of Alix and Ashtin throughout their childhood accompanied by a recent video of Ashtin celebrating her 21st birthday.

“Only big sisters understand this feeling,” Alix wrote in text over the video. “Shes growing up 😭💗.”

Thomas enjoys playing with Alix

As Alix’s youngest sibling, Thomas pops up on her TikTok from time to time when the family gets together. In a September 2023 episode of Call Her Daddy, Alix’s brother hopped on the mic and thanked her for playing with him and his toys.

“I really love her a lot,” he said. “And I appreciate that she plays dinosaurs with me.”

Penelope likes making GRWM videos with Alix

In a May 2023 TikTok video, Alix and Penelope did their makeup together for a Mother’s Day dinner. The influencer shared that Penelope is a horseback rider while giving her tips on makeup.

“So, Penelope is my little sister, she’s 8 years old,” Alix said, adding that her sister wanted to move to Miami to live with her. “I think she’s gonna come have a lot of sleepovers in my new place.”

She even admitted that “in terms of personality,” she was the most like Penelope out of all her siblings. “I look like Ashtin, but I act like Alix,” Penelope added.

Alix enjoys showcasing her family in moderation

Despite being known for her honesty, Alix values keeping parts of her relationships with her family out of the public eye. The podcast host told ELLE that there wasn’t much she wouldn’t post to social media, except for conversations with her loved ones that are meant to be “private.”

“Obviously, conversations with my friends and in relationships, and with my family, all of that’s private,” she said. “But I kind of give the brief overview of everything. I don’t think there’s anything specific that I try to stay away from.”

Alix's sisters walked the Sports Illustrated Swimsuit runway with her

In June 2024, all three of Alix's sisters joined her on the runway after she was named Sports Illustrated Swimsuit's first digital cover star. They started the day off walking the carpet alongside Earle before they joined her on the runway.

While Alix first walked herself, she then came out with Ashtin, Penelope and Izabel, all of whom also donned bathing suits in various colors for the runway.

"Opening for the @si_swimsuit swim week show AND getting to walk it with my sisters is such a dream come true 🥹🫶🏼 ," Alix wrote on Instagram of the special moment.
