UPDATE 1: Photos of the wedding are at the bottom of this post!

Ashlee Simpson has decided to tie the knot. She is marrying her boyfriend, Pete Wentz. The wedding is suppose to take place today in Ashlee's new Vera Wang wedding gown.

It's also interesting to note that Tony Romo will be attending the wedding as Jessica Simpson's date. They split up earlier this week, but yesterday they had lunch together and today they will attend Ashlee's wedding together. Jessica Simpson is the maid of honor in her sister's wedding.

People magazine paid over $1 million for the exclusive rights to take photos at the wedding. If they leak, we'll have them here.
