The reality TV star, 53, was pulled over by police in Malibu, California in the early hours of Thursday (04Oct12) and booked for driving under the influence and driving on a suspended licence.
Her representative played down the arrest and blamed it on a glass of champagne Bollea had had on an empty stomach at an event shortly before getting behind the wheel.
Now her lawyer, Raymond Rafool, reveals Bollea was also on antibiotics to treat the bacterial infection at the time of the run-in with cops, which likely exacerbated her intoxication, and she is full of remorse for the whole incident.
Rafool tells the New York Daily News, ""She regrets it. She's a mum, so she's embarrassed about it.
""She's just thankful it wasn't worse and thankful nobody got hurt. The police were all very nice. It wasn't a scene at all. It was anti-climatic.""
Bollea was freed on $5,000 (£3,125) bail.
