"They're not together just to keep this brand going. They have all the money in the world anyway and the fame isn't ever going to be a problem for them."
When asked if he thinks it is likely Posh and Becks will be celebrating their 20th wedding anniversary, he says it is a certainty.
"I'd put money on it. I think we can take it for granted that David and Victoria Beckham could possibly be together for ever."
But if it did all end tomorrow - would Brand Beckham still bring in the bucks?
Although Victoria remains the only Spice Girl not to have secured a number one solo single under her Gucci belt, her newly chosen career in fashion seems to be going well.
"The next progressive step for her was to launch her own catwalk label, which she's done very slowly, very carefully," says fashion designer Scott Henshall.
"I think it's very important that she didn't do this in the UK. She's shown this in New York - which automatically makes us Brits think she's even more fabulous."
According to him, the incredible success the pair have had as a couple is all down to Mrs Beckham.
"It's Victoria who is constantly pushing forward onto the global stage. I think the Spice Girls is almost a footnote now for her.
The Beckhams were welcomed into the LA glitterati
"Victoria's world stage is the red carpet."
He describes her as a "true icon" and says a lot of people would be surprised at how funny she is.
"She's very down-to-earth and she has a very dry sense of humour. I think she just wants to belong, I think she just wants to be accepted."
It seems David - or Goldenballs as Victoria likes to call him - has never had much of a problem being accepted within his profession.
"It's amazing how he can walk around in a sarong, a pair of pants or two ponytails, and it doesn't seem to have affected him a jot in terms of the way he's perceived within the sports world," says sports broadcaster Mark Webster.
"On a football field he expresses himself beautifully.
"It's an amazing achievement that David Beckham's come up with. He's kind of like the first guy to really nail it in in terms of football and everything else.
"He has taken it to a completely different level."
