The Beckhams have an art collection and are friends with Sam Taylor-Wood, so they may well have an interest in art beyond the financial aspect.
But I'm sure they would have entered the Louvre discreetly if they'd have wanted to.
Ones they've coloured in themselves presumably.
IIRC they're supposed to have a big collection of Damien Hurst's stuff, but as most of it's produced en masse
by his minions, it's not a guarantee of quality. With them it's probably just being able to say ''Oh, I've got a half-mill Damien Hurst in the dining room'' and not having any real appreciation for art like lots of nouveau riche celebs.
