In Hollywood, there are at least two sides to every story that ever hits a magazine, television show or internet website that is tracking these stars. In many cases there are even more sides as every person who was in a 2 block radius saw what happened and is willing to share their story so they can somehow be seen by the whole world. Everyone wants to have their part and everyone wants their piece of the pie, but no one is actually going to tell the whole true story for fear of it being boring or that they were watching what was happening through different eyes.
So, make sure you have a filter and the ability to find out what it is that will keep you going and will keep the readers happy and the stars on their toes. Just know it is not all true and that there are some things that just could not possibly happen.
