Former republican vice presidential candidate Sarah Palin went rogue with Oprah Winfrey, commenting on Levi Johnston's new-found fame, her time on the campaign trail with a pregnant teenage daughter and how she feels in hindsight about the infamous Katie Couric interview.

Palin appeared on "The Oprah Winfrey Show" on Monday to promote her already bestselling book Going Rogue: An American Life. She opened up about the father of her grandson who has publicly bashed her, saying that Levi's "aspiring porn" career -- referring to his deal with Playgirl magazine -- is a "bit heartbreaking."

"I believe he goes by the name Ricky Hollywood now," she jokes to Oprah. "He's quite busy with media tours. ... That's Levi's gig right now."

Regardless of their differences, Palin says she realizes Levi is still a teenager and that he will "forever be the father of this beautiful baby," her grandson Tripp.

As for Bristol, Palin says that her daughter was "devastated" and "embarrassed" when the media got word that she was pregnant. "I was naive to think that the media would leave my kids alone," Palin says, reflecting on her time on the campaign trail. She recalls that she never wanted her daughter's pregnancy to be "glamorized."

Another memorable moment as a VP hopeful was Palin's interviews with CBS anchor Katie Couric, who Palin refers to as "the perky one." The former Alaska governor says that during those interviews she was "annoyed" and felt that her words would be twisted no matter what. "Her agenda was not necessarily to show me in the best of light," Palin says of Couric. "If people only know me from that interview, I don't blame them."

Palin's new tell-all book Going Rogue: An American Life hits bookshelves Nov. 17.
