Not Sir Paul McCartney. He has formed a close bond with Sabrina Guinness, a former girlfriend of Prince Charles and heiress to the drinks dynasty.
The couple have been in regular contact in recent weeks and Sir Paul has gone so far as to ask her on a date.
Which is why at 8.30pm on Wednesday night, he found himself shuffling nervously on Miss Guinness’s doorstep in West London.
Inside, the 52-year-old socialite had spent the best part of an hour getting ready for his arrival.
She would, however, have been unruffled at the prospect of a former Beatle at her door. After all, her previous dates over the years have included Mick Jagger, David Bowie, Bryan Ferry, Jack Nicholson, Michael Douglas and Rod Stewart.
Miss Guinness opened the door and exchanged a kiss and hug with Sir Paul before they went inside.
They emerged moments later and jumped into his chauffeur-driven Lexus, heading off for a double date with Sir Paul’s daughter, Stella, and her husband Alasdhair Willis.
Friends say they had planned a low-key night at The Cow gastropub, just across the road from Stella’s £1.5million townhouse.
They set off towards the pub, just a few minutes’ drive away.
But when they realised photographers had spotted them, they circled the streets for around 30 minutes.
Sir Paul, 64, eventually asked his driver to pull over on the Portobello Road and dropped Miss Guinness at a friend’s house, before meeting up with Stella and Alasdhair on his own.
The three then dined at an Italian restaurant in Notting Hill where they chose a window seat – presumably so the photographers gathered outside could see that Miss Guinness was no longer with them.
Earlier, Sir Paul had said of the planned date:
“I realise everyone wants to see me with a new bird right now and that’s very flattering. I have known this lady for a while. We enjoy each other’s company.
“When we get together we talk about stuff like the environment and Al Gore, things like that. We have similar views.
“I have had a terrible day at the office and as you probably know I’m going through a pretty difficult divorce right now too.
“I just fancied going out for a few drinks to relax. We’re meeting up with my daughter and that’s that.
“It’s not really a big thing, we have known each other a long time.”
Sir Paul, Stella and Alasdhair left the restaurant at around 11pm and took a taxi to Stella’s home before Sir Paul went on alone to his house in St John’s Wood, North London.
