Mercede has signed on with Playboy ...
Mercede Johnston, the younger sister of Levi Johnston, has decided to follow in her brother's footsteps. The Alaska teen is giving the adult entertainment realm a whirl by posing for Playboy magazine - with the details still being worked out.
The lovely brunette has a blogspot and seems to enjoy taking an occasional swipe at her nephew Tripp's mama Bristol Palin.
Her brother, who plans to run for Wasilla mayor in October 2011 to impress his son Tripp, made a quick buck by posing for Playgirl in a shoot that did not show full frontal nudity- check out the November 2009 male pinups.
