Tina & Diana: Separated at Birth?

With the publication of Tina Brown's book, The Diana Chronicles, the media is talking about how Princess Diana's rise and fall paralleled Tina's career.

As editor of Tatler, Tina emerges in the public's consciousness as Diana rises in popularity; Tina even gets married three weeks after Diana does in 1981. Tina reigns as editor of Vanity Fair and The New Yorker as Diana grows sophisticated and media-savvy.

And then in 1997, Diana dies in a Paris car crash. I won't Talk about any specific similarities, but what happened to Tina's career shortly after? What what about the more obvious parallel? Just how much did these blonde Brits look alike? A certain amount of the physical resemblance is genetic but the hairstyle they shared was no accident.
