You're behaving as if she's some major cultural figure or something! She's a nice-looking, photogenic former party girl who got married and settled down and needs some publicity for a new jewellery range, hence the photos of her looking photogenic, with her photogenic kids in a photogenic setting. It's just good PR vis SM.
I think you fundamentally misunderstand the press. They're just interested in what sells. It's not some mark of approval. I had a photographer friend years ago in my London days who started working for a tabloid. At one point he spent days at a time parked on his motorbike outside the Beckhams' commuter-belt house, waiting for them to go in or out. He'd have done the same for anyone whose photo was in demand. If a complimentary story is likely to go down better, they'll do that. If a CHELSY TWO STONE HEAVIER AFTER SPLIT WITH HAZZA-type story was likely to go down better, they'd do that.
It's not the result of studying CD in depth and deciding that she's a good egg!
