Well slap our ass and call us Sally -- cops are on the lookout for "Party Down South" star Mattie Breaux after her drunk driving arrest last year ... TMZ has learned.
Law enforcement sources in Louisiana tell us, a judge issued a bench warrant for her arrest last month ... after Breaux failed to show up for a pretrial hearing.
Breaux was arrested in September and charged with operating her vehicle while intoxicated. Cops say they pulled her over because she was weaving all over the place.
Girl does love her drink.
