Mercede Johnston of the Wasilla Johnstons—a girl famous for being the sister of a guy who put his dick inside the daughter of a lady who did not become vice president—is following in her brother's autoerotic footsteps, and posing for Playboy. Page Six reports:

GOP presidential hopeful Sarah Palin and her family are the subjects of a profile by George Gurley in the September issue of Playboy, according to sources. Insiders say the story will run next to a four-page nude pictorial of Mercede Johnston, the sister of Bristol Palin's estranged baby daddy, Levi. […] Playboy sources say that Mercede is outspoken in the article about Palin and Bristol, whom she routinely lashes out against in her blog.

That is a reference to the brilliant MercedeJohnston.Blogspot.com. (Apparently she let MercedeJohnston.com lapse. Oops!) Most recently, Mercede zing'ed Bristol thusly: "Bristol misnamed her book. It should read 'Not Afraid Lies.'" Cannot wait for this girl to fight her way onto a season of Celebrity Rehab, or something. These are the Wasillans of our lives.
