While some details are confirmed, others have everyone speculating. Here's what we think you can expect this Friday when Kate and Will get married.

The Arrivals

In addition to Kate and Will's friends from university, Will's air force buddies, foreign leaders, church officials, and diplomats, celeb guests will include Victoria and David Beckham (pictured, left), Elton John, Guy Ritchie, and Joss Stone.

The majority of guests will arrive between 8:15 a.m. and 9:45 a.m. Will and Harry will arrive at 10:10 a.m., followed by foreign royals. Kate's mom, Carole, will arrive at the Abbey's VVIP entrance at 10:30 a.m., just before Will's family (including the Queen) arrives. The bridesmaids and pages will show up 10:55 a.m., and then Kate and her father, Michael, will arrive via the Queen's Rolls Royce Phantom.
