We all know that "reality" shows rely on heavy editing to make things interesting. But how far can they go until it isn't even reality anymore? This week's episode of MTV's "16 & Pregnant" has Kathleen Green -- grandmother of this week's "baby daddy" Isiah ---- furious.

According to TMZ Green said MTV "defamed" her family because "nothing that aired is what happened" in real life.

She tells TMZ that MTV set up shots and did major editing on the episode where she was featured along with the teen couple of Isiah -- her grandson -- and his baby mama Christinna.

The part that Kathleen is the most upset with is a scene where she bought a DNA test for Christinna. She believes that she came off as cold hearted because MTV never revealed a key detail in their situation. Kathleen tells TMZ "They didn't show that [Christinna] had told us she had sex with some other guy."

Kathleen tells TMZ that she and her family plan to sue for defamation.
