What IS Camilla saying to have Jilly and Prue so agog?

BONKBUSTER queen Jilly Cooper was thrilled to be reunited with her old friends the Duchess of Cornwall, 70, and Great British Bake Off judge Prue Leith, 78, at the National Literacy Trust’s 25th anniversary in London this week.

Jilly, 81, who looked elegant in a white frilly blouse and pearls, tells me: ‘Prue is a very old friend, but I hadn’t seen her for 20 years. It was heaven to see her. We used to be great friends but we drifted apart because of work. Camilla’s a great friend, although I hadn’t seen her since Cheltenham last year.

‘We both told Prue how thrilled we were about her being on Bake Off. Camilla loves it.’

Later on, Camilla asked for book suggestions before she flies to Australia next month. ‘I didn’t have any recommendations for her — how terrible,’ adds Jilly. ‘But you know what these parties are like — so frantic.’
