Jameson's car hit a light pole just after 1:30am, and after being given a field sobriety test, she was arrested on the spot.

No other cars were involved in the wreck.

The mother of two and wife of UFC star Tito Ortiz suffered minor injuries in the crash.

Despite a few scratches, Jameson refused to be taken to the hospital for observation.

We're told Jenna is no longer in custody.
