Avril Lavigne married Deryck Whibley this weekend in California. I am really happy for her and I wish the two of them health and happiness. But my mom side is screaming. "How old is she? She is just a baby." I got married at 24 and I thought that was really young for this generation. But 21... wow. Good luck Avril.

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.  (source)
