Spice Girl Victoria Adams--better known as Posh Spice--wed English soccer hero David Beckham today at a 15th-century Irish castle in a ceremony shielded from the prying eyes of the press and fans.

Adams reportedly wore a diamond-and-gold coronet that outshone royalty.

Only 29 family members and friends--including the three other members of the British pop group, "Baby Spice" Emma Bunton, "Sporty Spice" Melanie Chisholm and "Scary Spice" Melanie Brown--witnessed the wedding. Geri Halliwell, the former Ginger Spice, who quit the group 13 months ago, was not there.

Strict security surrounded the nuptials, prompted by a deal reportedly worth $1.6 million giving the British celebrity magazine OK! exclusive rights to what it called the wedding of the decade. A long white tent shielded guests and the couple from other journalists.

What Adams, 25, and Beckham, 24, wore for the occasion was a closely guarded secret--but publicists offered other tidbits.

Bishop Paul Colton of the Church of Ireland performed the ceremony. Adams, reflecting "girl power," didn't promise to obey Beckham in the vows. The couple's 4-month-old son, Brooklyn, attended. As the bishop pronounced the couple man and wife, a purple flag was hoisted with the entwined letters V, D and B.

Sir Elton John, who had been invited to perform at the reception, had to cancel his appearance, the couple's spokeswoman said. The British rock legend was suffering from heat stroke after getting too much sun during a concert tour in Italy, she said, speaking on condition of anonymity.

[For the wedding dinner, guests sat down to a simple but hugely expensive menu of red pepper soup, turkey, Mediterranean vegetables, summer berries and sticky toffee pudding.

Adams wore a $160,000 gold-and-diamond coronet, the Sunday Times reported, saying it outdid the tiara that Queen Elizabeth lent to her newest daughter-in-law, the former Sophie Rhys-Jones, when she married Prince Edward last month.
