Prince William's former love interest -- the one who apparently caused the brief split between him and Kate Middleton -- is now married and her sister is dating none other than Prince Harry. The Daily Mail reports Isabella Calthorpe, wed Richard Branson's son, Sam on Wednesday on the family's game reserve in South Africa.
Calthorpe's half sister is Cressida Bonas who is Prince Harry's love interest. According to reports, Bonas invited Harry to attend the wedding, but despite original reports he would attend, he apparently declined the invitation.
While Prince William was not in attendance there were several other members of the extended royal family at the Calthorpe-Branson wedding. Princesses Beatrice and Eugenie, who are believed to have introduced Cressida and Harry, were on hand for the nuptials. The rest of the guest list at the so-called "nearly royal wedding" is said to have been star-studded.
Prince William reportedly pursued Calthorpe, an actress, when he and Kate Middleton briefly broke up in 2007. However, Calthorpe turned him down and is often referred to as the one who got away from William.
