"Big Brother" alum Christmas Abbott was arrested in Florida this week ... TMZ has confirmed.
Abbott turned herself into authorities Tuesday in Tampa, where she was booked for felony criminal mischief.
According to a police report, obtained by TMZ, Christmas drove to a Tampa gym back in August to confront her baby daddy's alleged side chick. Cops say that Abbott flew into a rage, asking all kinds of questions, and hurling a cup of coffee. She then rammed into the chick's car in the parking lot.
Per the report ... Abbott called the other woman a "pathetic home-wrecking little slut" among other insults.
