Sarah Palin isn’t happy about Levi Johnston’s decision to model nude for Playgirl magazine. Palin referred to Johnston’s “aspiring porn” career as “a bit heartbreaking,” on yesterday’s “The Oprah Winfrey Show.” Johnston is the father of Palin’s grandson, Tripp . “I believe he goes by the name Ricky Hollywood now,” the former Alaska governor joked. “He’s quite busy with the media tours . . . That’s Levi’s gig right now.” Palin added that, despite his career aspirations, Johnston will “forever be the father of this beautiful baby.” Palin’s book, “Going Rogue: An American Life,” comes out today.
