"I started my day with a chipped tooth!" she reveals in the new issue of OK! "My wedding planner snuck me out to the dentist! Thank goodness it was fixed within the hour."
Fortunately, everything else went smoothly for the 22-year-old bride as she tied the knot with Mike Comrie last weekend in Santa Barbara, Calif.
Walking down the aisle in front of about 100 guests, Duff wore a Vera Wang gown with an organza mermaid look that was adorned with giant blossoms while carrying a bouquet of blush dahlias.
"There are not even words to describe it," says the starlet about her dress. "It's exactly what I imagined, plus 10 times better."
Duff says she also abided by the tradition of wearing something old, something new, something borrowed and something blue.
"I wore blue underwear and borrowed all of the jewelry [from Van Cleef & Arpels], and the something old was my great-grandmother's cameo, which I wore on the inside of my dress. The dress itself was new."
Upon exchanging vows, the newly married couple joined their loved ones under a muslin tent for the reception, which, according to Duff, featured truffled corn ravioli, pepper-crusted rib-eye steak and miso-glazed black cod, as well as a dessert station that included ice cream sandwiches with hot fudge dipping sauce.
Sounds like husband and wife are definitely off to a sweet start!
