Various American publishers have allegedly presented Katy Perry with several book deals offers to write a tell all book chronicling her many publicized relationships with John Mayer, Travie McCoy, her marriage to Russell Brand and her other famous exes, Mirror UK reports.

"I hear a number of American publishers are desperately trying to woo the 29-year-old pop queen into putting pen to paper with multimillion-dollar deals. And they are convinced her story would be a worldwide hit," the Mirror UK tabloid story reads.

Initially, it was Brand that was offered a tell-all book deal, which he later pulled out of, the Mirror UK source reveals.

"Katy thought that Russell was going to tell all about what they got up to in the bedroom -- but now she can breathe again, says the source. "Her main cause of concern was there wasn't any post-divorce agreement in place, leaving him to talk about her whenever he pleases."

But now that Brand has opted out of the book deal, Perry may take it upon herself to write her own tell all book which publishers expect to be a best seller given Perry's massive stardom and fame.

"She wasn't very kind to Russell when she spoke about him after the split and with her star at such a meteoric height, publishers expect her to be a ­bestseller," the Mirror UK source continues. "Her story and relationships are fascinating to many people in America, from her pop fans, Christian groups and star-loving book readers."

In addition to her relationships, Perry's alleged tell-all book will feature an inside look into Perry's strict Christian upbringing.

Prior to becoming an international pop star, Perry -- born Katheryn Elizabeth Hudson -- sung gospel music and grew up with Evangelical preacher parents, the Daily Star UK reports.
