In one clip, Beiber wavers as he tries to walk heel to toe, then stumbles slightly as he turns and appears to have his arms out for balance.

Attorneys for the 19-year-old singer persuaded a judge to withhold four clips depicting Bieber urinating in a cup for a drug test.

Bieber, whose birthday is Saturday, has pleaded not guilty to driving under the influence, resisting arrest and driving with an expired license after his Jan. 23 arrest in Miami Beach.

The next hearing is scheduled for March 4. The trial, originally set for March 3, was rescheduled to a later date.
