Eighteen-year-old Mercede Johnston may follow in her older brother's footsteps and pose nude for "Playboy" magazine.  Reports that Mercede will pose for the magazine later this month in Los Angeles have not been confirmed.  Mercede, like her famous brother Levi, hails from Wasilla, Alaska.

Levi Johnston posed for "Playgirl," although the magazine did not show full-frontal nudity.  Levi is also the former fiancé of teen abstinence activist, single mom, and former"Dancing With the Stars" contestant Bristol Palin.  You may also know Bristol Palin as the daughter of the former Governor of Alaska and author of "Going Rogue", Sarah Palin.  You may also remember that Sarah Palin headlined the Boston Tea Party rally locally in 2010.

Mercede Johnston has reportedly been working out and losing weight for the upcoming photo shoot.  She is perhaps best known for her blog, "The Official Blog of Mercede Johnston" in which she has written copiously about Bristol Palin and the rest of the Palin clan.  Surprisingly, "The Official Blog of Mercede Johnston" has only 23 followers.  Johnston does not write about a potential "Playboy" shoot in her blog.
