She has almost no revenue streams to speak of. The OF £250K came to nothing, although I now believe this was planted for a reason.
I think at the last count, she had been on 14 holidays, including one where she paid for business-class flights to Thailand.
Yes, she dresses like a tramp, but many designer items are supremely expensive. Louboutin trainers and designer handbags, of which there have been many.
Plastic surgery and hair and nail appointments will regularly make a huge dent.
The bills for the house. - £3k monthly heating bill, and if reports are correct, still meeting monthly mortgage payments
The big one - Legal representation
Clothes for the kids, ipads, and technology.
I could go on, but I'm sure you get the picture.
Mermaids are certainly hinting at the scent around KFP and her financial affairs.
