The beauty queen, 26, is facing drink driving charges.
Her lawyer has confirmed Saturday's (03Dec11) arrest after his client took to Twitter.com to protest her innocence, writing, "Let's clear things up now... I'm NOT in Michigan and I'm NOT in jail! Wrong Fakih."
The attorney, Doraid Elder, tells TMZ.com that Fakih is "very saddened and very apologetic for the situation that she's in right now."
Fakih was the first Arab American ever to be crowned Miss USA.
