Katie Holmes and Tom Cruise were married in a wacked-out Scientology ceremony in a fairytale Italian castle in front of over 150 guests tonight. Rose-scented candles lit the damp corridors of the castle, white flowers were scattered throughout, and Katie was said to be stunning in an off-the-shoulder Armani gown with Swarovski crystals. Guests dined on Italian hors d’oeuvres and an elaborate meal. The cake was multi-tiered white chocolate with marzipan roses.

It sounds like a dream come true for Katie, who once gushed to Seventeen magazine that she used to imagine marrying Tom Cruise when she was a girl.

The bride: Holmes wore an off-the-shoulder Armani gown with a train in ivory silk cadis adorned in Valenciennes lace and Swarovski beaded crystal embroidery. Holmes also wore an ivory tulle floor-length veil and ivory silk shoes. Armani, which outfitted the entire wedding, also supplied Katie’s bouquet of calla lilies, as well as a champagne evening gown, which she wore at the reception.

The groom: Cruise wore a navy blue Armani tux.

The couple’s rings: white gold Cartier with diamonds.

The meal: After cocktails, guests were served Italian hors d’oeuvres, followed by a multi-course meal.

The cake: Five-tiered white chocolate, decorated with marzipan roses, and studded with white chocolate chips.

The entertainment: Italian singer Andrea Bocelli.

Here are pictures of Katie arriving at Odescalchi Castle and looking out the window. [via] She sure looks upset at something, most likely the crowds outside. It could be a classic case of pre-wedding jitters, though. We wouldn’t blame her.

While I was quite fond of my conspiracy theory that Tom and Katie weren’t officially married, their rep says that they “officialized their marriage in Los Angeles prior to their departure for Italy.”

Update: Here are more wedding details from Star magazine. It really does sound lovely, although Katie’s face in these candids is kind of ruining it for me:

Katie wore an off-the-shoulder bridal gown by Giorgio Armani and carried calla lilies wrapped in leaves of galax and steelgrass. The gown featured a train in ivory silk cadis adorned in Valenciennes lace and Swarovski beaded crystal embroidery, featuring a delicate crinoline frill at the shoulders and a silk soleil border around the hem. Holmes also chose an ivory tulle floor length veil and ivory silk shoes.

Tom wore a navy blue two-button satin peak lapel single breasted Armani handmade tuxedo with flat front trousers and matching four-button vest. The tuxedo was complemented by an ivory silk French collar shirt, of the same fabric as the bride’s gown.

The wedding party included Isabella and Connor, Katie’s sister Nancy Blaylock as Matron of Honor and Tom’s best friend David Miscavige as the Best Man. Holmes’ two older sisters, her brother, and parents were also on hand, as were Cruise’s three sisters and mother Mary Lee. Katie was walked down the aisle by her father during the traditional marriage ceremony, which was performed by a Scientology minister.

After they took their vows, the couple celebrated with family and friends at a wedding reception which included colorful and elegant floral décor accented with red roses. TomKat was serenaded by world-renowned Italian vocalist Andrea Bocelli. Guests enjoyed a multi-course meal followed by five-tiered white chocolate wedding cake which was decorated with marzipan roses, and was studded with white chocolate chips and featured white chocolate mouse and white chocolate cream filling.

For the reception, Katie changed into an asymmetric champagne Giorgio Armani Privé evening dress made of silk organza and decorated in Swarovski crystal beads. It looks like Tom really did give Katie a fairy-tale wedding!
