Farrah Abraham — Pleads NOT GUILTY to DUI

Exclusive 0429_farrah_abraham_tmzFarrah Abraham has pleaded NOT GUILTY to her DUI — and her May 31st trial could be awesome … based on her list of excuses.

our sources broke the story … the former MTV “Teen Mom” (turned porn star) got popped for DUI in Nebraska, back in March.

Farrah”s attorney was in court this morning to enter a not guilty plea to all 3 charges she”s facing — aggravated DUI, refusal to take a field test and disorderly conduct.

Farrah blew a .147 — nearly twice the legal limit, according to the police report.

She went on our sources Live days after the arrest and claimed she did nothing wrong — that people had been feeding her drinks … she was “put in a bad situation” by her sister … was only re-parking her car … she had a sober friend with her … plus she had a bad cough and couldn”t blow properly.

Tell it to the judge, Farrah.
