I hope this news blurb is true, and I hope she studies design more, or returns to journalism, whatever. She's too smart not to do something extraordinary.
I think it's actually smart of her to lay-low for a bit. Find a purpose, revamp her image since it's been mass-marketed and stolen by so many, and make people hunger for her... as opposed to people beginning to tire of her, wonder what the hell she is doing with her life or doing at events like Cannes, and cringe over the fact that she is wearing a smock dresses and peter pan collars as she nears the age of 30.
She'll still be shot plenty by the paps, I don't think it's as if she's going to quit the celeb thing and move back to Hampshire or anything dramatic like some people are taking it. There's still her Madewell line and other commitments too, so no worries!
