Listings for an "Untitled Bristol Palin Memoir" were viewable Monday on Amazon.com (release date June) and an online catalog for HarperCollins (release date August). The listings have since been pulled.
Publicist Seale Ballenger of the Harper imprint William Morrow, the book's presumed publisher, declined to comment Tuesday.
Bristol Palin, daughter of former Alaska Gov. Sarah Palin, has become a celebrity herself through her appearances on "Dancing With the Stars" and as an advocate for sexual abstinence among unmarried teens.
The 20-year-old Palin is the mother of a 2-year-old, Tripp Johnston. She is estranged from the boy's father, Levi Johnston.
Palin told E! Online on Monday that she would "probably" run for office someday.
