nicoleweddingmore10.jpg Even though Nicole Richie's weekend nuptials to Joel Madden are being hailed as the celebrity wedding of the year (we're guessing it was because of the elephant), it sounds like there were a few headaches when it came to preparations last week!

The wedding was supposed to be on December 5, but a source tells X17online exclusively that as soon as Nicole learned the media was in on her big date, she "had a panic attack" and pushed it back to the next weekend. Nicole was also a bit frantic because her wedding dress wasn't finished, so she opted for the 11th, which is apparently her lucky number.

A source at the wedding tells X17online exclusively that brother-in-law Benji Madden made a very sweet toast, thanking Nicole for a beautiful niece and nephew and stating how thrilled he was to finally have Nicole as a sister in law. Aww! Benji also thanked Nicole for "completing Joel", and when Joel and Nicole exchanged their personal vows, father Lionel was very teary eyed and emotional.

Harlow' birthday is on January 11th, so we're glad Nicole was able to work it all out and give herself another lucky date on her annual calendar. Now if only she could sell those wedding photos...
