Pippa Middleton: Kate\'s Marrying William Was \'Just a Simple Family Wedding\'

Obviously, being an active participant can throw off one\'s perspective.

And while admitting that "it sounds funny to say," Pippa Middleton\'s matter-of-fact reaction to her sister Kate Middleton\'s marrying Prince William in the 2011 royal wedding was, simply, "We saw it as just a family wedding. And actually, I didn\'t realize, perhaps, the scale of it until afterwards."

For that matter, all the Middletons shared her understated response.

"We all took on the roles as any family would," Pippa said in an exclusive TV interview that aired on Monday\'s NBC

Seeing the TV cameras and, especially, she said, the throngs of people who had gathered to witness the wedding couple\'s kiss on the balcony of Buckingham Palace, Middleton, 30, recalled thinking, "Wow, this is pretty special."

The same sentiments abounded regarding her much-photographed maid-of-honor dress – which some fashion observers said helped to catapult the younger sibling into the celebrity stratosphere.
