2010 Miss USA Rima Fakih was HAMMERED when cops arrested her for DUI this weekend ... this according to Michigan police.
According to the police report, obtained by the AP, Fakih was initially stopped when officers noticed the 26-year-old speeding and weaving through traffic in Detroit early Saturday morning.
Cops say Fakih "immediately identified herself as Miss USA."
