Royal Wedding Spoof Goes Viral While Kate's Dress Remains a Mystery

A hilarious royal wedding spoof is burning up the internet. It's all part of an elaborate ad for T-Mobile, and it worked. The video has gone viral, getting more than 4.5 million views on YouTube alone.

In the video, dead ringers for Prince William and Kate Middleton boogie down the aisle. Best Man Prince Harry busts a move with the bridesmaids before his brother leapfrogs over his head.

And actors who look just like Prince Charles and his wife Camilla dance down the aisle. Even the Queen gets into the groove.

Meanwhile, the guessing game over who is designing Kate's wedding gown is at fever pitch. Kate reportedly has three different dresses at the ready just in case any details about the top secret gown are revealed.

Amy Eisenger from weddingchannel.com told INSIDE EDITION, "Obviously the press is just hounding her to try and find out what she's wearing. But let's not forget that this is also a sentimental thing for her. She doesn't want William to see what she's going to wear before she walks down the aisle."

A recent survey named Kate one of history's most beautiful princesses. She's ranked #3 according to beautifulpeople.com, just ahead of Princess Diana at #4. But Kate comes in behind Princess Rania of Jordan, at #2 and the always gorgeous Princess Grace of Monaco, aka Grace Kelly, at #1.

Maybe her ranking will go up if she makes a royal entrance like the one in the T-Mobile video.
