Ray J was arrested in Beverly Hills last night.

The R&B star, who is Brandy Norwood's younger brother, reportedly got into a violent confrontation and spat in a police officer's face at the Beverly Wilshire Hotel. A law enforcement source told gossip website TMZ.com that police were initially called to the scene because the 33-year-old star made contact with an unidentified woman's butt in the bar.

Although it was determined to be "incidental" and not sexual battery, Ray J was asked to leave the hotel, but he allegedly became belligerent and refused to leave so security made a citizen's arrest. The situation is said to have escalated further when law enforcement arrived at the scene and the "I Hit It First" hitmaker kicked out the back window of the police car and spat in an arresting officer's face as he was being handcuffed.

He was booked for trespassing, resisting arrest, vandalism and battery on a police officer, and later released.
