Kate Middleton warns Pippa: Don't date Spencer Matthews' brother
But there's one person who isn't so happy about this relationship: Pippa's sister Kate.
Sources close to the Duchess of Cambridge, 30, say she's distraught over her 29-year-old sister's new dinner companion, fearing it'll strain their already fragile relationship further.
Not only is she concerned about 37-year-old James's reputation as a party-loving 'playboy', she fears any link with his cocaine-shame brother Spencer, 24, will cause yet more embarrassment to the Middletons.
'Kate's told Pippa before that she needs to think very carefully about how her actions reflect on her and the Royal Family,' says a source.
'She's now telling people she might have to distance herself from Pippa if she won't listen.'
