Sarah Palin wanted to go head-to-head with Tina Fey on “Saturday Night Live” over the objections of the show’s producers, according to a new book about the former GOP vice presidential candidate.

For her appearance on the NBC comedy show, aides tossed around the idea of having Palin play a journalist interviewing Palin, as played by Fey.

But they were “stunned” when SNL producers “balked at the idea of having Palin and Fey on camera at the same time for reasons that were not fully explained,” according to “Sarah from Alaska,” a new book that traces Palin’s rise in national politics.

Palin and Fey appeared on-camera together for only a few seconds during the Oct. 28, 2008, show.

Aides also “balked at her planned interaction with actor Alec Baldwin,” a well-known supporter of liberal causes who, in 2000, threatened to leave the country if George W. Bush was elected president.

On the show, Baldwin said to Palin: “Forgive me but I feel I must say this. You are way hotter in person.”

Palin’s campaign wanted her to respond with: “Hey weren’t you supposed to move to France after the election?” but the show’s producers settled on: “Oh thank you. And I must say your brother Stephen is my favorite Baldwin.”

“Sarah from Alaska,” by Scott Conroy and Shushannah Walshe, two reporters who were imbedded with Palin’s campaign, provides a sympathetic look at the former Alaska governor.

They write Palin “truly is a likable person” but her “lightning-fast political rise has fundamentally changed her in some unflattering ways.” Her “positive message of reform is unrecognizable” because she now “dwells constantly in an attack stance.”

The authors also write Palin expressed concern about the cost of her clothes before the figures were made public and note the clothing expense was a necessity.

They trace the clothing issue back to the day of the vice presidential announcement.

Palin’s children were not informed of their mother’s offer to join the GOP ticket. Instead they were told they were “going to Ohio to celebrate their parents’ twenty-fifth wedding anniversary.” Therefore they were all “tired, unprepared and underdressed” for the announcement.

The campaign hired stylist Lisa Kline to outfit the candidate and her family, which ended up costing $173,000, according to Federal Election Commission fillings. Kline told the authors: “They just said ‘Please get it done.’ To be honest with you, I didn’t look at labels. I looked at the job in front of me.”

She noted: “As a stylist, I have a lot of avenues to get discounts. I called everyone I knew. It was Labor Day weekend and there wasn’t a person around. Had I a month to do this, it could have been done for such a more reasonable amount of money.”

After Kline brought the clothes to the family, “Palin was one of the few people in the room who expressed concern over the exorbitant expense of some” of the items. So Kline and Palin’s assistant removed some of the price tags to keep her unaware of the cost, the book notes.

Palin’s memoir, “Going Rogue” is due out Nov. 17.
