Who Is Allie Bieber? Justin Bieber's Stepsister Is Growing up Fast

Justin Bieber catapulted to fame with his catchy music and colorful life. Fans couldn't help but also be curious about the people dearest to him. Get to know his stepsister, Allie Bieber.

Justin Bieber's mom, Pattie Mallette, was 17 years old when she became pregnant with him. She never married Justin's father, Jeremy Jack Bieber, who was her on-again, off-again boyfriend.

People around Pattie pressured her to terminate and end her pregnancy, which she revealed in her book "Nowhere But Up." But she refused to listen, a decision she does not regret, having given birth to a son who became a music superstar.

FACTS ABOUT ALLIE BIEBER

On March 1, 1994, Pattie gave birth to Justin at 18 years old. For the sake of their son, she and Jeremy have remained friends despite their breakup. Jeremy, who had his share of legal troubles, went on to date Erin Wagner.

Jeremy and Erin, who never married, share a daughter, Jazmyn Bieber, and a son, Jaxon Bieber. The former couple split up in 2014 after seven years together, but they continue co-parenting their children.

After his breakup with Erin, Justin's father dated Chelsey Rebelo, who had a daughter named Allie from a previous relationship. Jeremy and Erin tied the knot in February 2018, making Allie Justin's stepsister.

While Allie is Justin's stepsister, the "Peaches" singer's other siblings are his biological brothers and sisters.

Allie, who was born on April 7, 2007, has since become a fixture in Justin's life, with numerous social media posts devoted to their close relationship, including one taken at a recording studio.

Justin previously shared a sweet photo of himself, Hailey Baldwin, Jazmyn, and Allie. In the caption, the doting husband and brother called them his "favorite girls." Allie expressed her love for her stepbrother in the comments.
