Pop star Justin Bieber celebrated his 20th birthday with his family.

The "Baby" hitmaker's father, Jeremy Bieber, flew to the star's new home in Atlanta, Georgia, with his other children, Jazmyn, 5, and Jaxon, 4, reports dailymail.co.uk.

Justin turned 20 March 1. Jeremy, who reportedly split from his younger children's mother Erin Wagner recently after seven years, wrote on Twitter: "Happy Birthday son. Wow 20!"

Justin's mother Pattie Mallette, who split from Jeremy when the singer was two, also tweeted: "Happy Birthday you know who! I love you."

Justin will celebrate with his friends before he appears in court in Miami Monday to face charges for driving under the influence (DUI), driving with an expired license, and resisting arrest last month.
