We know her as a reality TV star, author, Bristol's mom, GOP darling and 'SNL' comedy muse. But for years, Frank Bailey knew Sarah Palin simply as: the boss.

Once Palin's trusted Chief of Staff, Bailey is breaking ranks and planning a new tell-all memoir-- according to a new AP report out of Juneau, Alaska -- based on his "thousands" of personal e-mails from his tenure working for the former Alaska governor, who was was inaugurated to the state's highest office in 2006 and abruptly resigned from the job in 2009.

A draft of the book, tentatively titled 'Blind Allegiance to Sarah Palin: A Memoir of our Tumultuous Years,' has leaked to reporters, with excerpts circulating the Internet. Meanwhile, Bailey's team deny involvement in the leak.

The manuscript allegedly states that Palin, before resigning as governor, wrote to Bailey and another aide, "I hate this damn job."
