Prince William was spotted on his way into Westminster Abbey in London yesterday while Kate, Pippa and their mum, Carole, left their home in Berkshire to head to Central London where Kate continued on to Clarence House. Pippa and Michael Middleton followed behind in another car as the group arrived for final wedding rehearsals. The bride-to-be was seen unloading boxes and a dress bag from her car before entering the palace through the visitors gate. She and her family are taking care of last-minute preparations before the big day, while Queen Elizabeth II was wrapping up her own royal duties in the afternoon.
