Pippa Middleton: Why is everything always about Kate?
Pippa Middleton had been hoping to 'break America' with a series of interviews about her party planning book Celebrate this week, but Prince William put a stop to her US tour.
He wants to protect his and wife Kate's privacy.
Pippa, 29, last week told a friend she found it all deeply unfair, tearfully complaining: 'Why is everything always about Kate?'
'Pippa was so excited about all the US promotion they were lining up,' says our source.
'She was looking forward to the chance to put across the real her and was even considering moving there.
'It's not just about the money. She's more gutted that she can't do what she wants.
'Pippa's always there for Kate but doesn't feel like she's got her support when she needs it.'
The latest tension has upset the sisters' mum Carole, 57, too.
'She hates how things are between them now,' adds our source.
