Mark Frith's book Celeb Diaries, which hits the shops in autumn, claims to expose the celebrity world of the noughties.
Publisher Ebury Press has briefed Taylor Herring to deliver a national consumer campaign for Celeb Diaries.
The agency is planning to target high profile chats shows, radio programmes, and newspaper and magazine features as well as targeting showbiz blogs and entertainment sites.
The book comprises stories about various celebrities including Victoria and David Beckham, Jude Law, Amy Winehouse, Take That and Jonathan Ross.
Frith stepped down from his editorship last month to write the book. He was credited with taking Heat magazine from imminent closure in 2000 to a celebrity gossip bible selling over 500,000 copies weekly.
Agency account director Bryony Watts will report to Ebury's PR director Sarah Bennie. Edbury also published Piers Morgan books The Insider and Don't You Know Who I Am.
