The former porn actress pleaded guilty yesterday (16.08.12) to one charge of DUI following an incident in which she crashed her car into a lamppost in Orange County, California, on May 25 but won't spend any time behind bars according to gossip website TMZ.com.
She was arrested following the incident when she was asked to take a field sobriety test and failed it by showing signs of intoxication.
Prosecutors in Orange County say tests showed her blood-alcohol level was .05 percent above the legal state limit.
Jenna originally pleaded not guilty to the charge and another of driving without a valid licence, but the second count was dropped due to her guilty plea.
At the time of her arrest, Jenna is said to have had alcohol and prescription DRUGS zolpidem (Ambien) and buprenorphine (Suboxone) in her car.
The 38-year-old sex symbol - the star of numerous adult films such as 'Udderly Ridiculous' and 'I Love Lesbians 10' - suffered minor injuries in the accident.
