And he's spending 10,000 pounds flying out a team of top chefs from London's trendy Japanese restaurant Nobu to cook for her in Spain.

Posh fell in love with the vintage necklace when she saw Keira Knightley wear one to the Oscars last month.

It glitters with diamonds, rubies, sapphires and emeralds¡ªand we've shown how it would look on Victoria. The England captain and Real Madrid star has now spoken to Bulgari about buying a one-off copy.

But David also threw a surprise Japanese-themed party for Victoria's 32nd birthday tomorrow.

Elton John and partner David Furnish are tipped to make a surprise appearance.

Victoria's favourite food will be served up at their Madrid mansion, which will be decked out with beautiful Japanese silk wall hangings.

And we can reveal the sumptuous 11-course, 200 pounds-a-head menu, which will be overseen by Nobu's head chef Mark Edwards.

Appetisers include Posh's favourite edamame, a low-fat soya bean dish, and scallops. Next is seared salmon salad with Japanese sugar tomato and matsuhisa miso followed by shrimp and white fish sashimi, which is served raw and thinly sliced. Then it's langoustine spicy shiso martini¡ªlobster tails in a spicy salad sauce, served in a martini glass.

Also on the menu is grilled sea bass, low-fat seared steak, skewered beef, dumplings, exotic fruits and sorbet desserts.

There will also be birthday cake with green tea and chocolates.

A pal said: "Nobu's is Victoria's favourite so we know she will be thrilled."

David has also taken time off to take Victoria away¡ªthey're expected to go to the Italian lakes.
