The wedding wasn't exactly what most would call traditional, with Avril revealing before the wedding that it would be a one-of-a-kind experience for her guests--perhaps starting with the fact that the bride wore black.
Now, the singer is opening up about just how fun the festivities were, telling Chelsea Handler "I don't remember much of that, either!"
Still, she does remember some of the details (perhaps from the planning process) and she spills about the venue (a castle!), the bachelorette party and some of the other cool stuff that happened during the three-day event.
Watch the video above to hear Avril's share all of the wedding deets, plus she explains how she and Chad have set specific rules to make their marriage work.
