RadarOnline has all the sexy, stunning and even shocking (those hats!) details about the fashions at the Royal Wedding.

Prince William & Kate -- Modern Royals Driving Toward The Future

Princess Bride Kate Middleton is the fairest today as she wed Prince William. Reigning over all the others in her stunning Sarah Burton for Alexander McQueen wedding gown, Kate regally showed off her diamond tiara and earrings.

Sister Pippa’s slinky, clingy and elegant white bridesmaid dress threw convention to the wind – and she wins sexiest dress of the wedding award.

Pretty princesses they may be, but the couture hats Beatrice and Eugenie were wearing probably even shocked their stunningly dressed grandmother, Queen Elizabeth.

Prince William and his blushing bride Kate truly are modern royals.

Instead of taking yet another carriage ride after the ceremony, William and Kate jumped in a snazzy Aston Martin convertible complete with a license plate that read: "JU5T WED."

Picture perfect Kate Middleton had a last minute rehearsal just two days before her royal wedding.

Wearing a pink cowl neck sweater under a cream blazer, with jeans and black sling-back wedge heels, the Princess-to-be carried a small bouquet of flowers and showed off her sapphire and diamond engagement ring. In one photo Kate was carrying a large black garment bag.  What her wedding dress will look like has been the most guarded secret kept by the Palace.

Kate rehearsed for the wedding previously with her future brother in law Prince Harry while her future husband William was away at work.

Westminster Abbey, the iconic church where Prince William and Kate will marry in front of 1900 guests, is currently closed to the public. A royal spokesperson told Reuters that the practice ceremonies will likely be going on the next two days, even if the bride and groom are not present.

A Buckingham Palace guard has been relieved of royal wedding duties for posting rude comments about bride-to-be Kate Middleton on his Facebook page.

Guardsman Cameron Reilly, 18, called Kate a “posh bitch” on the social networking site.  “Hur and william drove past me on friday n all a got was a sh***y wave while she looked the opposite way from me, stupid stuck up cow am I not good enough for them! posh bitch am totally with u on this 1 who reely gives a f about hur,” he wrote, but has since removed the post.

Prince William and Kate Middleton are set to walk down the aisle Friday and RadarOnline.com decided to take a look at just how much it will cost and who is paying the bill.

Let's start with the fact that the heart-stopping price tag is now at an estimated $34 million, making it one of the costliest celebrations in history.

* Security: $32 million.  The British taxpayers are on the hook for this. Thousands of police officers will be stationed along the bridal procession route and military personnel will also be protecting visiting foreign royals and dignitaries.

* Wedding Ring: $11,000. Prince William opened up his own wallet to buy Kate a simple but elegant gold band.  Of course he didn't have to fork out for an engagement ring.  He gave Kate the one worn by his late mother, Princess Diana.  It is now valued at $1 million.

* Receptions: $600,000.  The Queen is hosting a luncheon reception immediately after the wedding for 600 of the estimated 1,900 who will attend the ceremony.  A lucky 300 guests have been invited to the dinner reception hosted by the father of the groom.

* Wedding Gown: $434,000. Kate's parents are paying for her gown, reportedly designed by Sophie Cranston, plus additional outfits she'll wear to the receptions.

* Wedding Cake: $80,000. Prince Charles is writing the check for the two cakes -- traditional cream for Kate and white fruit cake for William.  That works out to $134 per slice!

* Flowers: $800.000. The Queen and Prince Charles are sharing the tab to adorn Westminster Abbey and Buckingham Palace.

* Cleaning: $64,000. The British taxpayers get to pay for cleaning up after the one million people who are expected to come out and witness the big day.

* William & Kate's royal love:  Priceless!
