Backstreet Boy Nick Carter was arrested in Southern California over the weekend on charges of drunken driving, TV's Entertainment Tonight and Celebrity Justice report.
Carter, 25, was with friends at a restaurant in Huntington Beach on Saturday and was stopped by police around 7:30 p.m. after he pulled out of a parking structure and started driving on Main Street, according to the Smoking Gun Web site.
Carter was given a sobriety test, which he allegedly failed before being booked on a misdemeanor DUI charge. He was released several hours later.
"Nick Carter deeply regrets the current situation," the singer's rep said in a statement. "He is on doctor prescribed medication and was unaware of its interaction possibilities."
The news comes just as his group is back in circulation, having announced a 13-city tour starting March 21 in New York. As opposed to the large arenas they played in the past, the Backstreeters (who debuted in 1997) will now appear in intimate club venues.
Reps for their label, Jive Records, tell the Associated Press that the reunion tour will offer all the group's hits, as well as a few songs from their upcoming CD, their first together since 2000's Black and Blue.
Over the past few years, the group was all but retired, except for a few benefit performances, and in 2002, Carter released a solo album. Last December, Brian Littrell signed with Christian record label Reunion Records.
