Moll had time to kill before sitting down to Almodovar's latest movie The Skin I Live In at her local Curzon cinema in the King's Road. 'So I popped opposite over the road into my favourite punk boutique Ad Hoc, also known as "Boy",' she says. 'I take all visitors to London to this tiny outlet - it personifies everything that Chelsea was once world-renowned for: originality, flair, theatrical excess; in direct contrast to the dire conformity of Marks & Spencer further up the King's Road.'
There, she bumped into the Hollywood star - whom she'd never met before - and soon got on chatting terms with her and two of her children, daughters Zahara and Shiloh: 'To open the conversation I congratulated Angelina on her family. Not her beauty or her fame or her film performances. At rock bottom she is a mother.
'There were no nannies present. I assumed no security, but I later learnt that before Angelina's arrival, about eight Brangelina security men and women had checked the shop out first and had kept an eye on me when I approached.
'I liked the way she pointed out to the clamouring children that if they spent their pocket money on "fripperies", they would have none left for ice cream later - and they accepted this without demur.
'She responded eagerly when I said this was the very best shop in London for the young at heart, kids of all ages, confiding that she had been a customer there since the age of 14.
'On my departure I noticed they were being picked up by Brad who expressed admiration for my Andrew Logan brooch - my pulses quickened, I do admit that. His handsome features were those of a younger understudy, or a cloned minder, so maybe it wasn't Brad; but the effect was the same.'
How enchanting. A lovely celebrity encounter for a change. Coincidentally I have just completed Brad's and Angelina's horoscopes (not commissioned by them) and would say she is the disciplinarian of the two while he is the controller of purse strings. A pair built to last together despite periodic rumours to the contrary.
And if you didn't catch her Desert Island Discs appearance on Radio 4 earlier this year, click here to listen to it. She's at 13th if you scroll down the page.
PS I learn from Ad Hoc, that after Moll had left the shop, Angelina asked the staff who that 'wonderful, extraordinary lady' was. Now she knows.
PPS Molly is now certain it was Brad Pitt at Ad Hoc and not a security man. She has examined recent shaved pics.
