BORIS JOHNSON

may know about everything from the Heathrow expansion to Ancient Rome, but he was totally baffled when he tried to take a selfie with Geri Halliwell. In fact, the former Spice Girl had to take over – as my own photo, above, shows – telling Boris: ‘Here, I’ll show you how to do it!’ Flustered and star-struck, all BoJo could utter in response was: ‘This is a legendary moment for me – I am meeting Geri Halliwell.’ Her reply? ‘It’s Geri Horner now, thank you!’ The singer is preparing to release a folk album next year under her new name – she married Red Bull F1 boss Christian Horner over the summer.
