Pamela BachDavid Hasselhoff's ex-wife Pamela Bach has begun her jail sentence, TMZ reports.

Bach was convicted of her second DUI last week, and she will be serving three months behind bars in a Los Angeles prison. The actress actually turned herself in early -- she wasn't expected until next week.

According to PEOPLE, Bach also violated the terms of her probation from a previous DUI, and therefore won't be able to drive for two years once she's released.
