Madonna has revealed she was on the verge of giving up on her movie about Wallis Simpson but changed her mind after being given "a sign" - on a removal van.
But during an interview with Graham Norton to be screened later this week, she said she was on the verge of giving up with new film W.E. due to frustrations with book rights - until the van encounter convinced her.
"I had gone through lots of trials and tribulations to the rights to a book about her (Wallis Simpson) and couldn't get that," she said.
"I thought 'what am I doing here, writing a story about somebody... are the royal family going to hate my guts for telling this story?'"
Madonna said she was questioning whether to carry on and "doubting everything", but her opinion was changed when she spotted the vehicle.
"The doorbell rang and I answered it in my pyjamas, as I do. There was nobody there but there was a removal van and it said Montague Removal.
"That was her maiden name - and I thought 'right, that's a sign'," the chart queen added.
Madonna also said she could foresee a time when she may decide to marry again.
The singer-turned-moviemaker has been married twice before - to actor Sean Penn and then film director Guy Ritchie. Asked if she could see herself saying "I do" again, she confirmed: "I could actually."
Madonna also revealed her new album, due for release in March, will be called MDNA.
