According to court records, he pleaded not guilty on Wednesday to those charges in a written plea submitted by his lawyer. If convicted, Bieber could face up to six months in prison, although experts say he is likely to receive a lighter sentence because it would be his first offence.
Bieber is scheduled to make a court appearance on Feb. 14 to formally answer the charges. He was also charged with driving on an expired license and resisting arrest without violence.
Bieber, a native of Ontario, Canada, first shot to fame as a child when his mother posted YouTube videos of him singing. He became a musical and social media sensation with a devoted following of young, mainly female fans.
The "Boyfriend" singer's life off-stage has been rocky in the last year with problems ranging from scuffling with paparazzi in London to a felony investigation into whether he pelted a neighbor's house with eggs in his gated community near Los Angeles.
Also On Wednesday, a online petition asking the Obama administration to deport Bieber after his Miami arrest from the United States, passed the 100,000 signature threshold required for a White House response.
Bieber was unlikely to be deported because federal law dictates that a visa can only be revoked or denied for a conviction of a violent crime with a minimum one year prison sentence.
