The Secret Diary of Pixie Geldof

TROUBLE'S brewing in the Geldof household . . .

I gather newlywed PEACHES has got the hump after finding out little sister PIXIE has been keeping a secret diary of their wild family life.

A pal told me: "Peaches didn't know. There's a lot of sensitive stuff in there. The family's been through so much over the years and Peaches is really worried."

I'm not surprised. With all the Geldof goings-on there must be enough material to fill a tome or two.
