Justin Bieber celebrated his 20th birthday with his family in Atlanta, Georgia on Saturday (01.03.14) and is expected to enjoy a huge party before appearing in court in Miami on Monday (03.03.14).
The 'Beauty And A Beat' hitmaker's father, Jeremy Bieber, flew to the star's new home in Atlanta, Georgia with his other children, Jazmyn, five, and Jaxon, four, to help him mark the occasion on Saturday (01.03.14).
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. Xoxo"
Justin will reportedly enjoy a party with his friends before he appears in court in Miami on Monday (03.03.14) to face charges for driving under the influence (DUI), driving with an expired license and resisting arrest last month.
But the 'Boyfriend' hitmaker is said to have sparked concern among some of his pals since moving from Los Angeles - where he had a schedule set up by people connected to his business affairs - to Atlanta, as he no longer has any real rules or plans, with insiders claiming he spends much of his time smoking marijuana or consuming sizzurp, a cocktail of Sprite, Jolly Tancher sweets and medications codeine and promethazine, which is referred to by the singer and his pals as 'lean'.
A source previously said: "He is constantly high. Drinking more lean, smoking more weed than ever."
