Why? The dress, of course!

Read on to find out...
"I hope it's Alexander Mcqueen like everybody's been saying," Goreski told us at Us Weekly's Hot Hollywood party. "I think it will give it a little bit of drama. It will be a statement piece for her, and I think it's a really nice tribute to an amazing British designer."
What about Will?
"Could you imagine if he showed up in sequins?" Goreski laughed, pointing to his own black sequined blazer. "It's going to be in the U.K., [and] they have amazing menswear and great tailoring. He's going to look so handsome."
As for whether or not he'll watch the nuptials, Goreski admitted, "If I can stay awake. But the other thing is, those photos are going to run like you've never seen a photo run before!"
Celebs who will be watching?
"I think it's very exciting and I'll definitely watch it," Kim Kardashian recently told us.
Heidi Klum is also on the list of Hot Hollywood royal wedding watchers. "I think that I'm going to watch, yeah," the supermodel mom said. "[But] I don't think I'm like obsessive about it as so many people are. At the end of the day, they're in the public obviously and so a lot of people know about it. From the outside looking in, I think that they make such a sweet couple and I'm happy for them."
As for Dancing With the Stars cohost Brooke Burke?
"I am, but I'm going to watch it in the morning over coffee with my girls and try to explain to them that their wedding will never look like that," Burke said. "It's fantasy and it's a princess."
