Amber Portwood is out of the slammer -- for now.

A day after going behind bars in a Madison County, Ind. jail on a domestic violence arrest, the Teen Mom star, 20, was released after bail was posted for $5,000.

According to TMZ, Portwood pled not guilty on four counts related to several alleged attacks against Gary Shirley, her ex-fiance, in front of Leah, their 2-year-old daughter.

A Madison County official told Us that Portwood is barred from contact with Shirley, 22, until the case is resolved in court.

Portwood has been frank with Us Weekly about her struggles with anxiety, depression and anger management. "I'm trying to put the pieces back together," she told Us.
