While Justin Bieber is a global superstar, away from the spotlight, he’s ‘Big Brother’ to a bustling, blended family. Though his family tree appears complex, the pop star’s heartwarming relationship with his younger siblings remains a core part of his life.
The pop icon’s parents, Jeremy Bieber and Pattie Mallette, split shortly after his birth. While his mother raised him as an only child, his father went on to have several more children, giving the “Peaches” singer a wonderful group of younger half and stepsiblings. Here is a breakdown of the impressive “crew” and what they’ve been up to lately.
The Bieber Family Roster
Justin, born in 1994, is the eldest. He has a total of four younger siblings: three half-sisters and a half-brother, plus one stepsister. All the younger children are on his father, Jeremy Bieber’s, side of the family.
The Half-Siblings: Jazmyn, Jaxon, and Bay
Jazmyn and Jaxon are the children of Justin’s father, Jeremy Bieber, and his ex-partner, Erin Wagner. The two share an incredibly tight bond with their older brother.
Jazmyn Bieber has grown up in the public eye, often appearing on her brother’s social media throughout the years. This year, the now 16-year-old took a major step toward building her own brand by launching her first fragrance.Jaxon Bieber
Jaxon Bieber
Jaxon Bieber, a handsome and fashion-forward teenager, is often seen documenting his travels, fashion flair, and boxing sessions on his social media. He recently marked a significant academic milestone, graduating from middle school. His close relationship with his older brother was highlighted when they attended Coachella together in 2025.
Bay Bieber
The youngest of the half-siblings is the adorable Bay Bieber, who was born to Jeremy and his current wife, Chelsey, in 2018. The little one is already a social media star, engaging in cheerleading and kid modeling. Her favorite song, according to a recent sign, is still her big brother’s debut hit, “Baby”—a sweet detail that melts the heart!
The Stepsister: Allie Bieber
Technically Justin’s stepsister, Allie is Chelsey’s daughter from a prior relationship, but the family fully embraces her. The 18-year-old is incredibly close with her siblings and Justin’s wife, Hailey, with Justin affectionately calling her one of his “favorite girlsss.” Allie has even joined the pop star in a recording studio, hinting at shared musical talent.
