Jaime Pressly, who was reportedly almost three times over the legal blood alcohol limit, was released on $15,000 bail and subsequently charged with two counts of DUI.
She entered her plea during a court hearing at a Los Angeles County courtroom on 4 February (11) and is next due in court on 18 March (11).
If convicted, the actress faces up to six months in jail.
Meanwhile, Jaime Pressly reportedly owes $637,149 in unpaid taxes. She is also in the midst of divorcing entertainment lawyer Simran Singh.
But she's upset that people are linking her marriage to her other problems - and she wants to protect her three-year-old son from the lies.
She tells TV news show Extra, "People are thinking my divorce is happening because of the (DUI and tax) situation. Truth is, these are all isolated incidents."
She's also upset about remarks that have been made in the media about her parental skills in the wake of her current issues, stating, "(These are) ridiculously unkind and untrue (allegations). I don't ever want my son to grow up and read all these false statements.
"(My husband and I) fell in love quickly. We got married very quickly. It didn't work out the way we wanted to. There's nothing more to it."
