Mercede Johnston is letting it all hang out in the September issue of Playboy. Levi Johnston's 18-year-old sister has posed nude for the men's mag, and blasted her brother's almost-mother-in-law Sarah Palin in the accompanying interview.
"I think she'd have had a mental breakdown" if she'd become president, Mercede told interviewer George Gurley. "As governor she quit on us. What does that say about her?" Mercede took on her her brother's baby mama,Bristol Palin. She claimed that after Bristol found out she was pregnant, she sent Levi a text message that said, "Ever since I found out I was pregnant, I prayed to God you weren't the father."
