A new book about Sarah Palin claims she had sex with former NBA player Glen Rice in 1987, according to the National Enquirer.

The book written by investigative reporter Joe McGinniss, who rented a house next door to the Palin family as part of his research, says the former Vice President candidate had relations with Rice when he was a junior basketball player for the University of Michigan.

Rice, who led Michigan to a national championship in 1989, was in Alaska for a college basketball tournament and allegedly hooked up with Palin who was then a TV sports reporter. The book claims the tryst happened only nine months before Palin married her husband.

The book, titled The Rogue: Searching for the Real Sarah Palin, claims she had a fetish for black men at the time, according to the Enquirer, citing a publishing source. The book won't be available on store shelves until Sept. 20, but the Enquirer claims Rice confirmed the relationship to McGinniss.

Rice would later go on to play in the NBA for a host of teams, including the Miami Heat and Los Angeles Lakers, while Palin would transition into a political career after her stint as a sports reporter.

McGinniss has also written critically acclaimed books about Richard Nixon and Teddy Kennedy. McGinniss initially went to Alaska to do a story on Palin for Portfolio magazine, but ended up netting a book deal about the controversial conservative.

Palin strongly opposed McGinniss moving next door to her and posted on her Facebook at the time, Wonder what kind of material he'll gather while overlooking Piper's bedroom, my little garden, and the family's swimming hole?
