I don't believe all I have read about their wedding and it's costs. The Daily Mail have been obsessed with it, about 20 articles today. The fact is, it's a private affair and they know nothing, they're just making it up but whatever they have spent, it's up to them as her parents are millionaires as are his and her husband is very wealthy as well.
I feel sorry for Pippa as well. A while ago I watched an interview she gave on American TV and she said she doesn't like the media attention and she gets upset when she reads things about herself online and she likened it to bullying. I also read that the boyfriend she had at the time of William and Kate's wedding dumped her as he didn't like the media attention she received.
