She can feel frustrated if she likes.
The difference between her and another famous person e.g. Professor Stephen Hawking or even Beyonce is that she has specifically made a fortune out of being a 'Domestic Goddess'.
Not just a good cook like Delia or a proper chef like Gordon Ramsey, but, no, a domestic goddess no less.
So somebody who manipulates the public with such patronising sounding tomes like 'How to Eat' oh do fuck off is surprised when the public react to the news that her life is not perfect.
No woman should be subjected to domestic abuse ever, but by goodness, HAD the myth of domestic goddess fallen away for some other reason eg she was spotted stuffing her face with McDonalds every night or eating a Greggs pastie and feeding her precious kids fruit shoots, well it would be nice to see that smug grin taken away.
A multi-millionairess. Never has to earn a penny, could spend her time volunteering for charities OR something more useful.
But, no, the most important thing is baking blardy cupcakes. 
Like I said, HAD the public's blinkers been removed as regards her perfect life because we found out she used Tesco value ham and didn't really have an orgasm over a set of fairy lights, then I would have a major case of schadenfraude.
