Former Alaska Governor Sarah Palin says she was "shocked" when the McCain campaign revealed that her daughter Bristol was pregnant and then declared that the Palins were happy to see their daughter have a child.

Appearing on Good Morning America to promote her book Going Rogue, Palin continued on a theme she touched upon in her book: The tensions between herself and the McCain campaign during last year's presidential election.

News of her daughter Bristol's pregnancy "was released to the media before I could talk about it and before Bristol could talk about it, and that was unfortunate because teenage pregnancy is a problem in America and we did not want it to be glamorized," Palin told ABC's Barbara Walters. "And the McCain team had sent out the message that Todd and I were giddy happy to become grandparents, and I was shocked when I saw that statement. I said 'no, no, no, that's not the message that we want to send.'"

Palin made similar comments during her interview with Oprah Winfrey, which aired on Monday.

"If we [the Palin campaign] had been given that allowance to deal with the issue in a more productive way, we perhaps could have sent a better message about -- this is not to be glamorized," Palin said. "It's not to be emulated."

Palin also told Walters that the father of the child, Levi Johnston, doesn't have any dirt on her as he now claims. Late last month Johnston told CBS News that he knows things that could "hurt" Palin, but wouldn't divulge them because he didn't want to go "that far."

"He doesn't have anything on me," Palin said.

Johnston also alleged that Palin referred to her son Trig, who has Down syndrome, as her "retarded baby."

"That's heartbreaking, to know that he would say such a thing, and that's not true," Palin told Walters.

On Monday, NBC News reported that Nicole Wallace, a former aide to the McCain campaign, said all the conversations recorded in Palin's book are "fabricated," because Palin never recorded or took notes of conversations with McCain staffers.
