Justin Timberlake’s world tour detoured to Sag Harbor, N.Y., on Friday, when a judge suspended his driving privileges in New York while he fights a drunken-driving charge.

Appearing in local court by video conference, the pop singer pleaded not guilty to the misdemeanor for a second time. In July, his lawyer had objected to how the initial paperwork was filed and asked to have the case tossed. Instead, prosecutors refiled the paperwork, and Mr. Timberlake was arraigned again.

The celebrity saga has brought crowds to Sag Harbor. Reporters, camera crews and paparazzi have descended on the town to attend court appearances in the case’s early days, whether or not Mr. Timberlake was present.

Defendants usually must appear in person, but Village Justice Carl Irace said on Friday that it would be unfair to make Mr. Timberlake show up for the same proceeding twice. Mr. Timberlake is scheduled to perform in Antwerp, Belgium, on Saturday.

Mr. Timberlake, who rose to pop stardom in the 1990s, was arrested and charged with drunken driving in June after swerving between lanes and running a stop sign in a residential neighborhood in Sag Harbor in the early hours of a Tuesday morning.

An arrest report said that Mr. Timberlake’s breath had a “strong odor” of alcohol and that his eyes were “bloodshot and glassy.” He told police officers he had drunk “one martini” before getting in his car, according to the police report.
