She was the mistress/"kept woman" to several wealthy men in London.
Benny Hill?
Many wealthy, older men might have wanted Miss Brown for a mistress but there is no evidence that she complied. She was a bright, pretty girl, when she left St. Anne's, Oxford University for London where she wrote for The Specatator and other publications. She was, is, an exellent writer, and very ambitious.
Her first big job, reviving the almost moribund "Tatler," was considered a hopeless assignment that few experienced editors wanted. Her success led to other successes in publishing in America.
She married historian Harold Evans who is twenty-five years older than Miss Brown, but not wealthy and not a member of the higher echelons of English society. Together they raised their two children and they are still together.
I'm not sure where you got your impressions of the young Tina Brown. There was never any scandal associated with her name, contrarily, she was highly respected for her work and for the rectitude of her personal life.
Her show was unwatchable because of the way it was set up: too many guests from different spheres, and the real stupidity and lack of intellectual breadth of her guests in relation to her sharp intellect and droll wit. I mean, just look at the list of guests her producer cites as "fabulous," probably some of the dumbest, most inarticulate escapees from a back ward.
The one pleasure of the show was seeing the rigid, polite expression on Miss Brown's face as she desperately tried to not burst out laughing at the rubbish she was listening to.
