The renowned hostess, celebrity PRO, TV regular and former debutante is this month launching her first book, The Party Bible, a step-by-step guide to party-throwing.
Rather aptly, Brewer is holding not one but two lavish launch parties.
The first, set for 24 March and hosted by publisher Artnik at London's reassuringly expensive Sketch - is described as a 'small soiree' of (only) 300 guests.
The second is being organised by Brewer herself on April Fool's Day at Sarasota.
Guests will include 'friends and clients past and present' - such as Dame Shirley Bassey, Cilla Black, Robbie Coltrane, Elle McPherson, Buzz Aldrin and Anita Roddick.
Even if armed with Brewer's book, followers will surely never match that guest list.
