Sir Paul So Happy He Strips
The high-profile couple were walking in Regent's Park, London when the 61-year-old singer decided to cool down.
And Heather, 35, was also dressed lightly for the time of year - just wearing a white skirt and white top.
An onlooker says, "They looked so happy, it was a real tonic just to see them.
"I must say though, I was surprised at how little they seemed to fell the cold. Maybe that's why they were clinging so tightly to each other."28/09/2003 10:42
