(Cover) - EN Showbiz - Katy Perry has been offered a 2 million deal to write a tell-all book about her life.

The 27-year-old singer is believed to have been approached by three publishing companies, who are all battling it out to secure a deal. It is believed the tome would offer a revealing insight into her failed marriage to British comic star Russell Brand.

"When everything was going well, Katy couldn't stop talking about him," a source told British newspaper The Sun. "Since the split neither of them have said anything keeping the price of a deal high."

Katy and Russell began dating in 2009 and got engaged following a whirlwind romance. The pair tied the knot in a traditional Hindu ceremony in India in October 2010. However, just 14 months later Russell filed for divorce citing "irreconcilable differences".

It has been speculated that Russell became frustrated with Katy's partying and they rarely spent time together due to their hectic work schedules.

Russell has previously released two books about his life. The former drug addict and womaniser is also believed to be working on a third tome, which is expected to cover the breakdown of his marriage.

Last year, it was reported that Katy's mother Mary Perry Hudson was planning to write a tell-all book. Mary runs a Christian ministry in California with her husband Keith and has previously revealed she didn't approve of Katy's raunchy song I Kissed a Girl.

Meanwhile, Russell is believed to have been named in a police report in Los Angeles.

A paparazzo alleges the 36-year-old actor snatched his cell phone and hurled it through the window of an abandoned building.

Photographer Timothy Jackson reportedly filed a report claiming "criminal damages" on Monday.

"Jackson claimed he was with a group of photogs... when he began to shoot Brand with his iPhone. Jackson claims Brand flipped out, wrestled the phone out of his hand... and then threw it at a nearby building, shattering a glass window," reports TMZ. (C) Cover Media
