EXCLUSIVE

Bella Hadid -- the 17-year-old daughter of Yolanda Foster -- ﻿who appears on "Real Housewives of Beverly Hills" -- was arrested early Tuesday morning for DUI ... TMZ has learned.

Bella -- whose stepdad is legendary music producer David Foster and whose dad is Mohamed Hadid -- was driving on PCH at around 4 AM when she allegedly blew through a stop sign and almost collided with an L.A. County Sheriff's Dept. patrol car.

Law enforcement sources tell us ... Bella was pulled over and the deputy detected a strong odor of alcohol.

Bella blew a .14 -- which approaches double the legal limit -- but because she's a minor it's even worse. She can't drive with ANY alcohol in her system.

It gets worse. Bella was driving on a suspended license.
