I just got word at 1:00 pm today from a Napa-based reader of SFluxe.com that the celebrities are starting to arrive in the Wine Country for the major multi-million dollar wedding of Simon Fuller, 47, and his longterm girlfriend Natalie Swanston.

“Already Annie Lennox has come in. She is so nice!” says the onlooker. “And rumor has it that Sting is going to be a guest as well. Should be a fun weekend up here!”

Other guests expected to arrive include Claudia Schiffer, David and Victoria Beckham (and all the other Spice Girls), Leona Lewis, and Simon Cowell.

Simon Fuller, creator of “American Idol,” is one of the most influential people in entertainment — and one of the richest, with a fortune estimated at $900 million.
