I think Britney Spears, Angelina Jolie, Jennifer Aniston, and other celebrities who have been dragged through tabloids would be interested in knowing that America apparently doesn't have that kind of thing.
She wasn't really famous in the States. That's fine, but there are absolutely tabloids tearing people apart there as well. And to be honest I think they would both be in for a rude awakening if they moved there. American gossip sights talk about these two as well. It is not just a British thing.
However, in terms of the public I think the stiff upper lip is perfectly acceptable. I don't know any job where people want you to come an discuss all your problems. That's just life.
