Thanks everyone for the post. So heres what happened last night:

After a couple hours of listening to the princess cry about not wanting to read the whole story (5 pages) I turned it over to DH and went in the other room and played legos with SS and my son. I let DH handle it. What followed was the biggest butting of heads yet. She stood right infront of him and cried that this isnt fair and she shouldnt have to do her report. Saying this with her tiara on! Next thing I hear is some yelling so I go out to the kitchen for a better listen. SD had the book and is balling her eyes out saying she demands that we talk to her teacher because this report is a paragraph summary and not a full page. DH grabbed book and read the story and said if she cant handle the story as it is with no Disney ending then though shit. So he grabs his copy of Grimms out of our room and makes her read aloud that version. }:)

6 hours later... its time for the kids to go back. Shes written 6 lines and almost every word is spelled wrong. We drop them off at BMs house and after DH gets in the van he looks and says hes done with SD. He doesnt want to be the mean parent but BM is such a waste that he has to pick up her slack. He decided that theres nothing to take away from SD, shes already lost everything, movies, mp3, phone, posters, cheering because of her grades and attitude. So he said he'll take her pride. Hes going to sit in class with her for a bit. Everyone in her class hates her cause shes so mean so it would knock her down a few pegs to have daddy in there. Or so he thinks. I honestly dont think it will work. Her teacher thinks SD has nothing to live for, that shes so lazy eventually she'll just die from lazyness. Im letting DH handle it his way. If he screws it up Ill be there for him but honestly this is beyond me.
