Katy Perry to spill the beans in book?

Los Angeles: Singer Katy Perry has reportedly been offered deals worth millions of dollars by US publishers to write a tell-all book.

According to mirror.co.uk, the publishers want her to write about her career and personal life, including her marriage to comedian Russell Brand and about her romantic alliances with John Mayer and Travie McCoy.

Brand may have shelved plans for a book detailing his marriage breakdown, but now Perry is considering her own tell-all tome.

Perry was supposedly concerned that Brand, her ex-husband, would reveal personal information about their marriage in a book of his own.

"Her main cause of concern was there wasn't any post-divorce agreement in place, leaving him to talk about her whenever he pleases. However, now the boot is on the other foot because Perry is being offered deals to come out and present her version of events," a source said.

"She wasn't very kind to Brand when she spoke about him after the split and with her star at such a meteoric height, publishers expect her to be a bestseller," source added.

Brand filed for divorce from Perry in 2011, following 14 months of marriage.
