EXCLUSIVE

Jasmine Tridevil -- aka the woman who went around claiming she had three boobs -- was busted early Monday morning for suspicion of DUI, but her BAC wasn't three times the legal limit ... JUST TWO!

Tridevil (real name Alicia Hessler) was popped by the Hillsborough County Sheriff's Department in Tampa, FL at 3:47 AM. She was booked into the Orient Road Jail a short time later. The strip search must have been awfully interesting.

According to the booking info, Hessler's blood alcohol content was .180 and .178 in two tests ... each more than twice the legal limit in Florida.

She is currently still in custody and being held on $500 bail.

Tridevil made the rounds last September when she went around claiming to have a third breast. To the surprise of no one ... she turned out to be a fake.
