0-j3loqx7r

Britney Spears is finally ready to open her Las Vegas show -- and sounds like it's gonna be awesome. But was it necessary for her camp to take a shot at Shania Twain? Who doesn't love Shania??

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.
