"Teen Mom" Amber Portwood.

It's been quite a year for "Teen Mom" Amber Portwood.

The 21-year-old MTV star was arrested Monday in Indiana after a judge issued a warrant for her arrest for violating her probation on felony domestic battery charges, according to the Associated Press. Portwood was convicted in June of assaulting her ex-fiance and 3-year-old daughter's father, Gary Shirley, in 2010 and was given a suspended two-year jail sentence.

The AP reports that the probation revocation was sought for Portwood after she was accused of battery and public intoxication in connection with a fight at a restaurant in November. (Portwood reportedly picked a fight with an unsuspecting IHOP patron.) She is also accused of not obtaining her GED or completing anger management classes as required, according to the AP.

Portwood will be held at Indiana's Madison County Jail without bail until her arraignment on Jan. 13. It's the latest of many setbacks for the "Teen Mom." In June, Portwood was hospitalized after attempting suicide and checked in to a Malibu rehab center to be treated for anger management issues and depression.

"I am going to rehab for anger control issues and depression," she told Star magazine at the time. "I'm on medication at the moment to just help me relax. I'm in a vulnerable state right now and I know people want a lot of answers."

Portwood's legal problems began in 2010, when she was shown hitting Shirley in an episode of "Teen Mom" and charged with assault.
