Teen Mom star Amber Portwood -- whose daughter Leah this week became of ward of the state in Indiana -- "threw a fit" because she can't spend Thanksgiving with the two-year-old, a source close to the mother told Breaking Celebrity News.

"They're all are spending it at Amber's grandmother's house but Gary and Leah can't be there with Amber," a source connected to the family told Breaking Celebrity News.

"Amber won't be able to see Leah today and last night was throwing a fit about it -- cussing Gary out when it was the courts decision to permit Amber with only supervised visits.

"She wanted Gary to bend the rules but he won't."

Leah was made a ward of the state as Breaking Celebrity News exclusively revealed -- and placed in the care of her father, Gary Shirley.

Breaking Celebrity News has also learned that authorities have classified Leah as a CHINS -- Child In Need Of Service -- thus making her a ward of the state.

DCS presented its assessment to a family court judge Tuesday and the judge made the determination to place the child with Shirley, with monitored visitations for 20-year-old Portwood.
