By the time Middleton returned to the Goring Hotel in London early Saturday from the wedding party at Buckingham Palace, there were three Facebook pages dedicated to her shapely posterior, the Daily Mail reported.
A correspondent noted that she appeared to be as popular with women as with men. Everyone was struck by her poise as she shepherded a flock of young bridesmaids and pages up the aisle in Westminster Abbey and supported her sister, now Catherine, duchess of Cambridge, throughout the day.
The sisters wore dresses for the ceremony from the same designer, Sarah Burton of Alexander McQueen, and had their hair styled identically.
Pippa, 27, works for her parents' company, Party Pieces. Like her older sister, she went to Marlborough College, an English private school, and then went on to study literature at the University of Edinburgh.
The Sun reported Pippa attracted the attention of one high-ranking member of the wedding party, the best man.
"You do look very beautiful today -- seriously," Prince Harry told her.
