Christina Aguilera tied the knot with music exec Jordan Bratman Saturday evening at Staglin Family Vineyard in California’s Napa Valley, Us Weekly says.

According to The Associated Press, sources told the magazine that Aguilera, 24, her hair decorated in jewels and pulled back in a bun topped by white flowers, walked down the aisle in a Christian Lacroix gown. About 130 guests watched the couple exchange rings. Bratman, 28, proposed to Aguilera in February while on vacation in Carmel, Calif. Their hotel room was filled with rose petals, balloons and gift boxes.

“When I got to the last box, there was a ring in it,” Aguilera told People. “He got down on one knee and said, “Will you do me the honor of being my wife?’ I’ve been floating ever since.”

WE’LL HAVE FRIES WITH THAT

Like many of you, we often feel a tad guilty about our expense-account lunches. Can we really justify those paninis and Cokes on the company dime?

Well, we just started feeling better about ourselves after hearing about the staggering $9,500 lunch that used-to-be-famous singer Olivia Newton-John had with British pop legend Sir Cliff Richard, along with Lord and Lady Ashcroft, at Nello in Manhattan last week. (For those of you who don’t know, Nello is a notch or two above the Olive Garden.) Those scoopsters at the New York Post learned that the meal included $500 of Kobe beef with truffles, $350 of risotto, and a single $3,500 bottle of wine. The foursome left a $1,400 tip.

That does it. We’re going for extra cheese on the Whopper at lunch today.
