Tara Reid has checked herself out of rehab less than one month after entering Promises Treatment Center.

The 33-year-old actress left the treatment center in Malibu, Calif., on Saturday and is doing well. Her family is "very positive about this being the new beginning for her" and is "taking steps to do everything they can to help Tara keep on the right track," according to People.

When Reid entered rehab in December, her camp would not disclose what she was being treated for.

Back in October, Reid told the magazine that she was a "social drinker" and enjoyed an occasional glass of wine, but that her partying days were over.

Do you think Tara's party days are in the past?
