Kate keeps breaking tradition — she and William have written their own personal message in the official wedding program! Read on for rehearsal details and more pics…

Prince William and Kate Middleton went to their final royal wedding rehearsal on April 28 at Westminster Abbey. While thousands of fans cheered from outside, best man Prince Harry, the bridesmaids and other family members joined in as the royal couple went through the run-down one last time.

William and Kate have also written their own personal message in the official program: “We are both so delighted that you are able to join us in celebrating what we hope will be one of the happiest days of our lives. The affection shown to us by so many people during our engagement has been incredibly moving, and has touched us both deeply. We would like to take this opportunity to thank everyone most sincerely for their kindness.”

On April 29, William, 28, and Kate, 29, will say, “I do,” but Kate has chosen not “obey” her husband. Like Princess Diana did in 1981, Kate has instead opted to “love, comfort, honour and keep” the Prince.

The couple have selected the Series One Book of Common Prayer ceremony, from 1966, which does not include the “obey and serve” clauses.

Archbishop of Canterbury Dr. Rowan Williams will conduct the ceremony, and Kate’s younger brother James will also do a reading.
