Dame Shirley Bassey's helicopter was forced to land in a school field after it got caught in bad weather.
The 70-year-old diva was flying home after performing at the Glastonbury Festival last night when her pilot decided to land the aircraft at Collingwood College in Camberley, Surrey.
Rosella Tew, 68, who lives near the school, saw the singer land.
She said: “I went outside to look because the helicopter was flying so low. It was also very misty and there were some very tall trees in its path.
“Dame Shirley must have a very good pilot. He managed to land safely but it could have been a disaster really.
“The pilot got out of the aircraft and came over to ask us where he was.
“Then Dame Shirley got out. She was dressed in a yellow raincoat and wellies.
“She asked us ’Do any of you live in these houses?’ and I said yes and offered to make her a cup of tea.
“But she said ’I don’t need a cup of tea, I need the bathroom’ and she went to the house of one of my neighbours.
“Dame Shirley was so lovely and so normal. After using the loo, she posed for pictures with us. She held my hand for a photo.
“She was quite calm and I could not believe how down to earth she was.
“I always expect these big stars to be all snooty but she was not, she was so lovely.”
She added: “I’ve always been a fan of Dame Shirley.”
Dame Shirley’s intended destination was the nearby Pennyhill Park Hotel and Spa, said college principal Jerry Oddie.
Following her unscheduled stop, she is thought to have stayed at the nearby hotel overnight.
Earlier yesterday, Dame Shirley had wooed the rain-soaked Glastonbury crowd as she brought a touch of glamour to the muddy festival in Somerset.
The Welsh legend thrilled thousands as she performed Hey Big Spender and The Lady Is A Tramp as the event drew to a close.
But even Dame Shirley was forced to amend her glamorous outfit so she could deal with the soggy conditions.
She got round the problem of the oozing mud by donning diamond-encrusted wellies bearing the letters “DSB”, keeping the rain off her feathered Julien MacDonald outfit with a dressing gown.
Glastonbury organiser Michael Eavis said: “Dame Shirley’s appearance was one of the highlights of the weekend.
“The sun certainly shone for Dame Shirley when she took to that stage.
“I hope her journey back didn’t spoil her enjoyment of the festival.”
