so far and almost to the end

I've been reading this book for a bit now I'm almost done with it. So far I have not been impressed with the writes craft or most of the syntax but its a somewhat interesting. Last time I wrote about the actual story was when Gracie was first told she had to lose the weight. And jack was starting to party every night with Adam. Now things have gotten better in some parts and worse in others.
Lets start with Gracie. She is starting to gain a fanbase that supports her weight lose struggle. Some support he cause and others support her curves. With this comes more paparazzi attention then she would like. Being still very new to life in hollywood she's not exactly prepared for the way the paparazzi treated her. Its making her rethink her decisions to be here but her relationship with jack helps her see that she needs to say.
Moving onto jack. He's going out with Adam most nights staying up late drinking and now more recently doing drugs. He is slowly losing his "good boy" reputation. He hasn't told Gracie yet but she is worrying more and more about him. Holly his manager is worried about him too. She knows about Adam's reputation and doesn't think that its a good idea for Jack to associate with him other then to work on this movie. He's starting to lessen his guard down with the paparazzi attention towards him and Gracie which is going to add to some bad news for them.
This poses some questions to my mind. Does this really happen to Hollywood stars? Are the paparazzi really that rude and intrusive? Why are stars using drugs when their lives are so good?
