Pippa Middleton dressed up to watch friends Camilla Hook and Sam Holland get married at Aberlady Parish Church in East Lothian, Scotland, today. She wore a red dress and netted fascinator and was joined by a female pal for the occasion. Pippa's been lying low since last month's controversial appearance in Paris where a guy friend pulled a fake gun on photographers during a drive. She's reportedly moved on from the incident with recent rumors that she's setting her sights on a move to NYC. Pippa also has her party-planning book, Celebrate, coming out in October. Meanwhile, sister Kate has been busy with royal engagements, including a reception with Princes William and Harry just yesterday.
