I remember this movie so clearly but not the title!

So, there’s a group of young adults, late teens, that go on a mission to find a movie producer that has made horror films and they want to interview him. These group of kids find his daughter who was a stripper and she takes them back to the house where all the films and things were made (she was the girl from her father’s movies) I remember them saying that. After they get to the house the end up becoming part of a horror film themselves. There was also a big man who had cut the skin of his face of and had sewn a baby face mask on to replace his actual face. Towards the end of the movie, the baby face man got one of the girls pregnant and the movie producers daughter killed her father. The movie producers daughter put a metal thing around a guys stomach (while video taping) and it would squeeze the guy until the skin bulged out if it… Then the girl took a knife and cut his stomach open and then took him into the barn with a bunch of other dead people sitting on what looks like pews and left him there to die while he watched the horror film he was trying to do a documentary. Please help me!!!
