Britney Spears and Kevin Federline’s marriage didn’t last long, but thanks to a new erotic novel inspired by the pair, their relationship will be immortalized forever.

According to Radar Online, Federline’s aunt, author Diane Story, has used the the ‘Femme Fatale’ singer as her muse for her latest release, ‘Pop Baby Krissy Doucet.’ The e-book is the first in a planned series, which focuses on the title character and her “sex, drugs and rock ‘n’ roll” romance with a dancer named Keenan Fazio.

“The moment Krissy set her sights on Keenan, she knew he was amazing,” the blurb for the book reads. “Choosing him at the club was one of the best decisions of her life. Yet how can she compete with the beautiful Tara Butler? A woman from Keenan’s past who understands his sexual desires. Would sharing Keenan in Tara’s bed be their only option for love?”

Spears and Federline were married on September 18, 2004, and after having two sons, they finalized their divorce in July 2007.

According to the author’s website, ‘Pop Baby Krissy Doucet’ will be available on April 26 for $4.99, and the next book in the series, ‘Pop Baby Maddy Fortin,’ will be released on May 30. We doubt the Spears-inspired novel will hit ‘Fifty Shades of Grey’ status, but sales may be increased due to an online contest Story has launched. Those who buy the book will get the chance to score a Britney Spears and Kevin Federline wedding invitation.
