Bad news for the notorious BFFs.
Justin Bieber's best friend Lil Twist was arrested for DUI—specifically marijuana—at 3:26 a.m. this morning while driving Bieber's Fisker Karma in Calabasas Calif., E! News confirms.
Per LASD spokesperson Steve Whitmore, Lil Twist (whose real name is Christopher Lynn Moore) was driving 69 mph and ran a red light before he was pulled over. The usual speed limit is 45.
While he was not driving in Justin's gated community, he was arrested on a street that leads to Bieber's mansion.
No one else was in the vehicle, which was towed after Twist's arrest. The car will be returned to Justin once someone pays the $260 fine.
The 20-year-old rapper was booked at the Lost Hills station, where he is currently being held on $5,000 bail. He will be released sometime today after he sobers up.
No court date has been set. A rep for Bieber declined to comment.
This is hardly the first time Bieber's fancy cars have made headlines.
Less than a month ago, the singer was accused of hitting a photographer with his Ferrari and fleeing the scene of the accident as he left a comedy club in Los Angeles with Lil Twist, although the LAPD later determined there was no hit-and-run.
Prior to that, Bieber's pals were pulled over while driving his Ferrari on Sunset Boulevard, and the driver was reportedly cited for driving without a license.
Police also recently visited the "Beauty and a Beat" singer's home following numerous complaints about Bieb's reckless driving, and a source exclusively tells E! News the neighbors called the cops because the star allegedly drove too fast while children were outside.
And in January, Justin's Ferrari was at the center of a tragedy after a paparazzo was killed by an oncoming car while trying to snap a photograph of the pop star's vehicle.
The 19-year-old star has also been making headlines for his questionable antics—most recently, he was caught on video peeing in a bucket while yelling "F--k Bill Clinton."
Luckily, the twosome had a nice chat and Justin apologized for his reckless behavior.
But it looks like he may need a bit more advice from his good buddy Bill.
