Edinburgh is readying for the royal wedding ceremony, of Zara Phillips and Mike Tindall this weekend.

Prince William's cousin is marrying rugby player Mike Tindall in Edinburgh, Scotland. The ceremony begins at 3 p.m.

According to the Daily Mail, the church, which is under heavy police guard, has been decked out with more than 400 white roses and hundreds of beech tree branches. Florists have also brought dozens of white carnations and white stargazer lilies into the chapel, along with small box trees and ivy.

Phillips, who is Queen Elizabeth's eldest grandchild, is said to be wearing Stuart Parvin, something her reps won't confirm. Similarly, there is no word on who'll form the bridal party

On Friday night, Friday night - which happens to be the 30th anniversary of the day William's parents, Lady Diana Spencer and PrinceCharles, married guests will gather at a pre-wedding celebration.

People magazine reports that younger guests are expected to party on the Windsors' retired vessel, the Royal Yacht Britannia, which is now moored in Leith docks.

The wedding of Phillips, 30, and Tindall, 32, whose engagement was announced last December, will mark the first time William and Kate have been seen together since their tour of Canada and Los Angeles earlier this month.

While in Edinburgh, the Duke and Duchess of Cambridge will be called by their titles in Scotland, the Earl and Countess of Strathearn.
