Pippa Middleton’s party role and what’s next for her

LONDON -- Pippa Middleton completed her spectacular rise to royal prominence with a vital role in ensuring that the royal wedding late-night party went off without a hitch.

After wowing a worldwide audience with a much-admired white dress during the official ceremony at Westminster Abbey, the stunning sister of Prince William’s new bride, Princess Catherine, kept the Buckingham Palace celebrations on course well into the not-so-early hours of the morning.

Pippa made sure that revelers kept their spirits and festivity levels high by injecting some welcome energy just as the party began to die down.

"You have to remember that everyone had been up since early in the morning, and it was an exhausting day," a female guest told Yahoo.com. "By the midway point of the evening, once all the formal stuff was out of the way, things needed a bit of a boost. That is when Pippa came into her own, getting people onto the dance floor and revving things up again. She was great!"

Comments regarding Pippa and her wedding day dress sent the Internet into overdrive early Friday, with Twitter being swamped with remarks about her looks and figure.
