Becks revealed that his and Victoria's first dates were in a Harvester car park in his BMW
The former England captain, who was playing for Manchester United at the time, says his first dates with Posh Spice were spent talking and kissing in his BMW.
They did this to placate Simon Fuller, manager of the Spice Girls, who wanted the relationship kept secret for as long as possible.
David spoke about meeting Victoria, their marriage and his illustrious football career with Kirsty Young on a special programme to mark the 75th anniversary of Desert Island Discs.

We stay together because we love each other
On his dates with the pop star, he said: “Her manager wanted to keep it quiet so we used to just sit in the car park and talk. I had this amazing BMW. I spent my whole pay packet from Adidas on this one car, but I was still living in lodgings.
“I picked her up and we used to sit in a Harvester car park. We used to just, you know, kiss of course and spend time together.”
Fashion designer Victoria and David have both carved out successful careers at the same time as raising Brooklyn, 17, Romeo, 14, Cruz, 11, and Harper, five.

He said: “We all know marriage is difficult at times. It’s about working through it.
“People have said ‘do we stay together because it’s a brand?’ Of course not. We stay together because we love each other, because we have four amazing children.”
He also revealed that United manager Sir Alex Ferguson, despite their tempestuous relationship, was the first person to call him after he was sent off in shame in a 1998 World Cup match.
