This is their first wedding run through at London’s historic Westminster Abbey and the last rehearsal for Prince William and Kate Middleton before the big day on April 29.

The Royal couple was seen Wednesday evening being ushered into the side entrance of Westminster Abbey, reported to conduct their final rehearsal for Friday’s much anticipated wedding ceremony.

They arrived in a chauffeur-driven car around 7:30 p.m., accompanied by some members of the wedding party including Prince William’s best man, his brother Prince Harry and Kate's younger sister, Pippa, her the maid of honor.

The future princess’s immediate family, including her parents - - Michael and Carole - - and brother, James were reportedly present to join them in the wedding rehearsal.

The New York Daily News said that the group was driven to Abbey ‘in a fleet of vehicles with blacked-out windows’ for the final run through of the service Friday expected to be viewed by billions of people around the world.

It was reported that throngs of fans began staking out outside Westminster Abbey yesterday, sparking fresh frenzy of what is considered the most talked about Royal Wedding of the century - - and the most expensive.

Prince William is tying the knot with commoner Kate Middleton after eight years together since they became a couple in late 2003. The two have known each other as classmates in Art History at St. Andrews University and began as good friends in 2001.
