If Medina seemed a little empty this weekend, it was because a few of the billionaires were in Sweden for the wedding of Charles Simonyi and Lisa Persdotter, a 28-year-old socialite and investment manager.

Bill Gates created a stir when he flew in Friday to usher the wedding of Hungarian-born computing genius and "the father of Microsoft Word," according to a juicy report in The Local, a Swedish newspaper, that was called out by The Huffington Post.

Other guests included Mick Jagger and Ulf Ekberg of Ace of Bass.

The events began Friday with a reception at Gothenburg's art museum, according to the story, which mentioned that "Gates was accompanied by a bevy of beefy Danish bodyguards as he passed through Copenhagen's Kastrup airport en route to the glitzy wedding to be held at the German church in Sweden's second city."

Also disclosed were more details of the bride Simonyi fell for last fall, after a longtime relationship with Martha Stewart.

Apparently he fell for the girl next door: Persdotter's parents have a place next to his vacation home in St. Tropez.
