Movie help? Crazy lady, maybe on Lifetime?

A few years ago I saw a movie, almost positive it was on Lifetime, about a crazy lady who takes in a pregnant girl and proceeds to hold her hostage because she wants her baby. The crazy lady's husband helps her, but eventually he decides she's wrong. So the crazy lady kills him and puts him in her blender. I believe the pregnant girl escapes with her baby or is rescued but I'm not sure. Please help! I've looked everywhere! Mom thought Kathy Bates played the crazy lady but I'm not sure. I've looked up her filmography as well.
