Last week, we reported that the Ashlee Simpson/Pete Wentz wedding was less than a month away, and today ET has revealed the date: May 17th.

The newly engaged couple will tie the knot at a private, undisclosed home in Los Angeles, a source said. About 120 guests have been invited to attend the shotgun nuptials, which will be kept private and hidden from the waiting media by large, fashionable tents – ala Beyonce Knowles.

News of Ashlee and Fallout Boy rocker Wentz’ engagement first broke to the media in early April.
