IMHO, the reason she's so desperate to fly to Oz (despite being heavily pregnant) is that she's getting desperate and the money is running out. I'm not suggesting for one second that she's a pauper on the breadline, but, her reputation has taken a massive nosedive, especially over the last 2 or 3years; she spends money like it's water, but she's not getting the level of press attention she was; no longer getting the OK exclusives, her TV shows have been axed by Living and the books have dried up. 'Designing' these hideous shoes is saying 'hey, Pwicceeeeeeeey's back and still doing well', when the reality of course is far from that. I reckon her fortune has probably halved.
All IMHO of course.
