LOS ANGELES — Pop star Justin Bieber was stopped in his white Ferrari today and cited for running a stop sign in Calabasas and driving without a valid California license, a sheriff’s spokesman said.

Bieber, 19, was stopped after he ran a stop sign at Parkway Calabasas and Prado de Las Flores about 4:30 a.m., sheriff’s spokesman Steve Whitmore said.

“I don’t know how many times he’s been stopped out there driving, but he has a history,” Whitmore said.

Bieber, a Canadian by birth, bought his Calabasas home at the end of June, according to TMZ.com. New residents of California are required to get a California license within 10 days of moving here.

But Whitmore said the license issue was not cut and dried.

“If someone has a residence in other state or country, he or she can have a license from that state or country as well as one from California,” Whitmore said. “But it was within the authority of the deputy who stopped him to issue him a citation for driving without a valid California license if he wanted and the deputy did just that.”

Whitmore said a friend who was following Bieber in another car drove the singer and his white Ferrari back home.
