Cat Deeley, the host of "So You Think You Can Dance" will be hosting CNN's coverage of the Royal Wedding alongside Anderson Cooper and Piers Morgan and tells BBC that she's pretty nervous.

"Apparently over 750 million people - I want to say thousand, but it's million people. I think I just vomited into my own mouth slightly - are going to be watching it," Deeley told BBC. "There's a week of festivities and fingers crossed it's going to be good."

Deeley will return to her native England for the coverage and admit she would probably be getting into some trouble.

"I'm just literally working all week, but if you do see some crazy blonde kind of being led out of Westminster Abbey by two burly security guards, one under each arm, going, 'I'm meant to be here!' you'll know it's me," Deeley said. "I'm going to try to sneak my way in."

Deeley, who previously hosted several British TV shows also sounded off on what Prince William and Kate Middleton's first dance should be.

"I would like them to dance to Alton Ellis' 'You Make Me so Very Happy.' It starts off all kind of slow... and then it kinds of kicks in a little bit and she could tuck her dress into her knickers and dance."

Deeley started her career as a professional model and has since been a presenter for MTV UK and hosted British series like "The Record of the Year," "Fame Academy," "The 2004 BRIT Awards" and "Stars in Their Eyes." Deeley began hosting "So You Think You Can Dance" in 2006, replacing Lauren Sanchez.

The Royal Wedding is scheduled for Friday, April 29.
