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.
