Justin Bieber has a Valentine's Day date with a US judge on charges of driving under the influence, resisting arrest and driving with an expired licence.

The judge in Florida's Miami-Dade County set a February 14 date for the 19-year-old star to appear. At the arraignment hearing prosecutors formally file charges and a plea is entered, although a defendant's lawyer can enter the plea in writing. Bieber might not be required to attend.

Bieber and R&B singer Khalil Amir Sharieff were arrested last week in Miami Beach during what police described as an illegal street drag race between a Lamborghini and a Ferrari. Neither has been charged with drag racing.

Police say Bieber admitted to smoking marijuana, drinking and taking a prescription medication.
