Katy nabs megabucks book deal

Katy Perry has signed a £2m (€2.4m) deal to write her autobiography.

The 'Firework' hitmaker - who is currently dating John Mayer - is expected to discuss in detail her 14-month marriage to British comic Russell Brand in the tome, which will be called 'Part of Me' because she wants to put out her side of the story before her former spouse releases the next instalment of his 'My Booky Wook' autobiographical series.
