Avril gets hitched

Avril Lavigne wed Sum 41 frontman Deryck Whibley on Saturday afternoon at a private estate in Montecito, Calif., a source confirms to PEOPLE.

At the outdoor, non-denominational ceremony, Lavigne was walked down the aisle by her father, John, to Mendelssohn’s “Wedding March.” She wore a Vera Wang gown and carried a bouquet of white roses. The couple said their vows under an awning decorated with white flowers in front of 110 guests, including family and friends from their native Ontario.

Once the groom had kissed the bride, guests tossed rose petals at the newlyweds as they walked back up the aisle. After the wedding, guests were to be treated to an outdoor cocktail hour before the reception, including a sit-down dinner, under a tent on the estate. In contrast to the all-white ceremony, the reception will have a red theme, with centerpieces of red roses and other flowers.

That's a pretty girlie dress for someone that made a living wearing a tie and a wife beater while riding a skateboard in the mall and flipping off old people.
