Weddings are notoriously expensive, but for celebrities that may have more than a few dollars to throw at such an event, they often go over the top.

2021 saw quite a few stars tie the knot, Paris Hilton, Heather Rae Young and Jennifer Gates among them.

While many kept their ceremonies intimate and low-key due to the ongoing pandemic, here's a look at some of the year's most lavish wedding celebrations.
