James Blunt brought Petra Nemcova. Perhaps the most interesting thing about him is that he's dating her.
He's a dork. This goes toward celebrity dork theory created by my friend Natalie. She insists that every celebrity was a huge dork in high school. (Think: Tom Cruise.) Then they become famous and... well, they're still dorky.
Which brings me to Ryan Seacrest. Don't you think he fits with the dork theory too?
