TomKat wedding watch

Tom Cruise and Katie Holmes braved rainy skies and hordes of fans and paparazzi as they arrived at the Odescalchi Castle for their wedding today. Holmes arrived ahead of her fiance, and was driven through the gates of the 15th-century castle in a limo. She was joined by Roberta Armani, niece of designer Georgio Armani, who created her dress - reported to be a strapless cream gown covered in thousands of crystals. Her bridesmaids, including Cruise's adopted daughter Isabella and Katie's sisters, will be wearing navy chiffon gowns. Cruise, wearing sunglasses, arrived in a van and waved to fans. At the Hassler hotel, where many celeb guests are staying, Brooke Shields drew gasps from fellow hotel guests as she headed to the ceremony in burgandy velvet. "This one was easy," she said of choosing a gift for the couple. "It was very clear what to get them." The cost of the event is estimated at over $2.5 million. Pics below are of Katie arriving at the castle, then looking nervously out the window, and Tom arriving a few hours later.
