The PR Gucci employee was the passionate romance of Wills' pre-Middleton days. Arabella and Will dated after meeting and sneaking upstairs at a holiday party in 2001. They only broke up to avoid a difficult long-distance relationship when the prince headed off to school. They remained real close when William would come home, so we're curious why she scored an invite to the wedding as well. Perhaps she can pull some strings with Gucci for Kate?
