Katy offered £2m for Russell book

Los Angeles - Katy Perry has reportedly been offered £2m to write a tell-all book about Russell Brand.

The former couple split in December after just 14-months of marriage, with Russell, 36, filing for divorce citing "irreconcilable differences".

Both have maintained a dignified silence since their separation, but three publishers are now said to be competing to get 27-year-old Katy's side of the story.

A source said: "When everything was going well, Katy couldn't stop talking about him.

"Since the split neither of them have said anything - keeping the price of a deal high."

Karl Lagerfeld

Meanwhile, Katy is rumoured to have moved on with 22-year-old Chanel model Baptiste Giabiconi - who she was spotted "flirting" with at Paris Fashion Week.

One person said to be thrilled about the love match is the fashion house's creative designer Karl Lagerfeld, who is believed to have played cupid between the two.

A second insider told The Sun newspaper: "Karl has a father and son relationship with Baptiste - he discovered him in 2008.

"He told Katy that Baptiste would be perfect for her and he was right as the pair hit it off straight away."
