With the recent flap over weddings at Napa Valley wineries, last weekend's nuptials between pop singer Christina Aguilera, 24, and music executive Jordan Bratman caused a stir in the county's planning department.

The couple and about 130 of their friends converged on Napa Valley last week for several days of revelry, culminating in the ceremony Saturday evening at Rutherford's Staglin Family Winery.

"A number of people have called," said Deputy Planning Director Steve Lederer, adding that everything appeared to be on the up and up.

Although a large white tent was set up outside the winery, the wedding was considered to be at the home of Garen and Shari Staglin.

"They are reportedly friends, which we have corroborated, and no money changed hands, so it's legal," said Lederer.

Garen Staglin said, "They're fans of our wines, and we were happy to provide the place for their wedding."

Staglin added they thought the event would be a bit more intimate, although it was limited to friends and family. "The problems were more with the people who weren't here," he said, referring to the press and paparazzi who hovered outside and above causing some disruption in the neighborhood.

Lt. Jean Donaldson of the Napa County Sheriff's Department said the patrol division had several calls regarding noisy helicopters above the scene and paparazzi parking on private property, but no arrests were made.

Aguilera termed wine country excursion "a destination wedding" taking place over the span of three days. "We are going to have a wedding weekend," she said to entertainment reporters prior to the wedding. "Each night has a certain theme to it, and the whole thing is very magical."

Aguilera arrived last Wednesday by private jet at the Napa County Airport and had a candlelight dinner with her fiancee at Yountville's French Laundry, staying well past the famous eatery's normal closing time of 10 p.m.

There was a Japanese-themed rehearsal dinner at Auberge du Soleil on Friday night.

The bride spent Saturday afternoon prepping in her $3,500 a night cottage at Auberge du Soleil and left about 3 p.m. for the Staglin estate in a limo. The ceremony itself took place shortly after 6 p.m., and the guests partied until past 2 a.m., although the newlyweds left earlier in Aguilera's $350,000 vintage white Rolls Royce Phantom, which was trucked up from Los Angeles. Staglin said things quieted down pretty well after darkness set in.

The location was kept a secret until the last minute, and guests were required to sign a pledge of secrecy. One attendee said, "You have to sign your life away. It's three pages long."

The document reportedly bans guests from discussing specific elements of the ceremony, including details regarding the cake, speeches and menu, but Staglin said the word got out when one invitee sold the invitation on eBay.

A gossip magazine reported Aguilera's invitation included the statement, "We are sorry to have to ask you, our dear friends and honored guests, to sign this agreement but we feel it is the only way to ensure the security of our wedding."

Lederer said the planning department periodically receives complaints or information that weddings or other social events are taking place at wineries. "When they come to our attention, we call the property owners," he said. "We always pursue them."

Lederer said several operations have been shut down, and race car driver Mario Andretti's Napa winery was cautioned to halt weddings. Andretti Winery has complied.

A controversy over events at the V. Sattui Winery will come to a head on Dec. 6, when the Board of Supervisors holds a hearing on a decision by the zoning administrator that weddings have not been historically allowed there.

Even the wedding planner for the Aguilera-Bratman affair could not discuss details. "I'm bound by a confidentiality agreement with the magazine that bought the rights," said Michael Gapinski. "It was really spectacular. It was a joy from day one when we knew it would be held in Napa. They're huge fans of Staglin's big reds."

OK, a celebrity news magazine, will publish its account later this week, after which people who attended can say more.
