Hilary Duff's weekend wedding to Mike Comrie couldn't have been more romantic, says her sister (and maid of honor) Haylie.

"What a special weekend filled with love and beautiful memories," she Twittered.

The 22-year-old Hilary (in Vera Wang) and the Canadian hockey player, 29, exchanged vows in front of 100 guests Saturday in an intimate ceremony in Santa Barbara, Calif.

Says a witness, "It was one of the most beautiful weddings I've ever seen. Absolutely stunning. They thought of every last detail and it was an incredible sight."

The couple, who began dating in 2007, got engaged this past February.
