Your average Christmas card might cost a few pounds, but if you happen to own one signed by Princess Diana then you’re sitting on a goldmine.

Two cards she sent to her godson Prince Philippos in 1989 have just sold at a Cirencester auction for £900.

But how they went under the hammer is a mystery as those close to London-born Philippos, 37, the youngest child of the last king of Greece, Constantine II, tell me he had nothing to do with the sale.

Jets turn Jess into a mess

Her hit song Hold My Hand has been the soundtrack to Jet2’s TV adverts for years, but singer Jess Glynne, right, admits she’s never taken a flight with the budget airline.

Jess, 34, is a very nervous traveller and scared of flying.

Perhaps some winter sun with her new girlfriend, sports presenter Alex Scott, 39, might be the perfect way for Jess to get over her phobia. Surely Jet2 would give her some free flights…

My congratulations to financier Ben Goldsmith and his restaurant owner wife Jemima Jones, who are expecting their fifth child together. Earlier this month I revealed that Ben, 45, had received personal praise from King Charles after publishing God Is An Octopus, a moving account of his grief following the death of Iris, his 15-year-old daughter with former wife Kate Rothschild.
