BOOTYFUL Model -- Charged with DUI

She couldn't walk a straight line, but last month ... she stumbled into our hearts -- and now, America's favorite, boozy, well-endowed model has been charged in connection with her infamous DUI bust.

You can thank us for breaking the story -- bootylicious SueLyn Medeiros was arrested in Hollywood on July 13th on suspicion of DUI ... in a freaking DeLorean ... all while wearing one of the skimpiest dresses we've ever seen. The footage speaks for itself.

Medeiros was officially charged with DUI recently -- and if convicted, could face up to 6 months in jail.

Her arraignment is set for later today -- when we expect her to plead "sexy."

DISCLAIMER: TMZ does NOT condone drunk driving ... no matter how hot you may be.
