Sistine Stallone is an American model, actress and podcaster — and the middle daughter of Sylvester Stallone. Where many famous children trade purely on a surname, she has built three careers in parallel: runway modelling, screen acting, and the hit Unwaxed podcast she hosts with her older sister Sophia.

Growing Up Stallone
Sistine Rose Stallone was born in Los Angeles in June 1998, the second daughter of Sylvester Stallone and his wife Jennifer Flavin, a former model and businesswoman. She grew up between her older sister Sophia (born 1996) and younger sister Scarlet (born 2002), with two half-brothers, Sage and Seargeoh, from their father’s first marriage. The sisters were raised largely out of the spotlight by Stallone standards — a deliberate parental choice — before being presented to the world together as Golden Globe Ambassadors at the 2018 ceremony.
Modelling Career
Following her mother into the business, Sistine signed with IMG Models in 2016, before she had finished high school, and quickly accumulated the credentials of a working model rather than a celebrity guest: a Chanel runway appearance, Dolce & Gabbana work and editorial features in Harper’s Bazaar, Town & Country, Teen Vogue and international editions of Elle and Glamour. She studied communications at the University of Southern California alongside the career, graduating into a fashion industry where her name opened doors but her portfolio had to justify them.
Acting: Sharks, Thrillers and Reality TV
Her screen debut came in the survival horror sequel 47 Meters Down: Uncaged (2019), playing Nicole in an ensemble of young actresses facing cave-diving sharks — a modest hit that tripled its budget. She followed it with Midnight in the Switchgrass (2021) alongside Megan Fox and Bruce Willis, and has spoken about developing her own writing, including a feature script, Scavenger Hunt. In 2023 the whole family went on camera for Paramount+’s reality series The Family Stallone, which ran for two seasons and recast the sisters as television personalities in their own right.
The Unwaxed Podcast
In 2020 Sistine and Sophia launched Unwaxed, a weekly podcast of unfiltered sister conversation — dating, family, embarrassment and occasional conspiracy theories — that became a durable hit and a business, with live shows and a loyal young audience. Their parents are the show’s favourite recurring guests, and the Stallone family dynamic, teasing and unscripted, is the product. Recording from New York, the sisters have built the podcast into arguably the most substantial enterprise any of the three has yet created.
Sistine Stallone Net Worth
Sistine’s net worth is commonly estimated at around $3 million, earned from modelling contracts, film and television work, The Family Stallone and the Unwaxed podcast’s advertising and live business. The figure is an unofficial estimate and separate from her father’s fortune, which is counted — as he would be the first to joke — in a different league entirely.
Personal Life
Stallone keeps her romantic life deliberately private, a stance she has discussed on Unwaxed while declining to feed it to the tabloids. Her public life centres on her sisters — best friends as well as siblings and co-hosts — her parents, and a large, carefully managed social media following. Of the three sisters she is often cast as the dry-witted middle child: model, sometime actress, full-time co-conspirator.
