Portwood's brother Shawn tells Us Weekly that "probation officers visited [her] for a random drug test at her house and they found pills in her purse that she did not have a prescription for even although she explained that they had previously been prescribed to her. In addition she missed a court hearing and that is why she was jailed this time around." Yikes!

Last June Portwood pled guilty to two counts of domestic battery after she was caught on camera assaulting her 3-year-old daughter Leah's father, Gary Shirley. Shawn added that his sister "is distraught because she was planning to spend Christmas with her family and Gary was going to let her see Leah also."

Portwood is due to face a judge on January 13.
