Britney Spears is finally ready to open her own Las Vegas show -- and people in her camp are saying it will easily surpass Vegas living legend ... Shania Twain!! Smart move? Plus, "Teen Mom" star turned porn star Farrah Abraham might have just proven she's the dumbest person in America. Is it even possible someone doesn't know who Trayvon Martin is??!! And, "Weeds" star Mary-Louise Parker wants to quit acting because bloggers are too mean to her -- so to make her feel better (and to torture Charles) we read the meanest things said about him on TMZ.com.
