MIAMI -- Pop singer Justin Bieber has a Valentine's Day date with a South Florida judge on charges of driving under the influence of alcohol, resisting arrest and driving with an expired licence.

A Miami-Dade County judge on Tuesday set a Feb. 14 arraignment date for the 19-year-old star.

In an arraignment, 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.
