I personally think the marriage has been dead in all but name for years. The Loos debacle sealed it and was a huge PR disaster for them.
I think they stay together because they genuinely love the kids and also because of Brand Beckham. Harper was a gift for VB.
All IMHO of course.
That's how I feel to. Though this is just a hunch, could be totally different. However the children do always seem to be really well turned out and well behaved. Even if their marriage is in the toilet they seem to be great parents.
I went to the Louvre plenty of times as a child and loved it. Then again I was constantly dragged around art galleries/museums ect, I remember really enjoying them.
