Forget Snooki — Mary Delgado may be the reality starlet most notorious for drunken run-ins with the law. The Bachelor winner was arrested for driving under the influence in Tampa, Fla., in the wee hours of August 12. Mary, who split from former Bachelor Byron Velvick last December after a five-year engagement, refused a blood-alcohol test and was later released on a $500 bond. The brunette was previously arrested on assault charges after a fight with her fiancé in 2007 and was busted again the next year for public intoxication, resisting arrest and disorderly conduct at a Texas bar. Hunky Byron proposed to Mary on the ABC reality hit's season six finale in 2004.
