Miguel, the guy behind the smash hit “Adorn” and “#Beautiful” with Mariah Carey - was arrested for driving drunk in L.A. early this morning.

Law enforcement sources say that California Highway Patrol officers initially flagged the 27-year-old singer’s 2013 BMW X6 for speeding and tinted windows on an L.A. freeway around 2:15 AM. 

During the stop, officers noticed the singer reeked of booze … and performed various field sobriety tests, which he bombed. 

Miguel - full name  Miguel Jontel Pimentel - also took a breathalyzer and blew a .10 and .11 … which is over the .08 legal limit in California.

Miguel was then arrested for DUI and hauled to a nearby station where he was booked and released a few hours later on $5,000 bail.

He is now scheduled to appear in court in September. So far there has been no word from Miguel’s camp.
