jane is above all of that gossip stuff
i don't know anything about her
but to a certain degree, 'above all that gossip stuff' = doesn't need the money
fact -> every time someone mentions her in a beatles book or film, they're making money off her
so if she, say, was in a state of financial desperation with medical bills or something - i wouldn't grudge her for writing a book
update - just googled her
it seems she wrote 3 top novels, is the president of several charities, has a cake decorating business and is an educated person of accomplishment.
way to go !
