The Celebrity Wedding: Joel Madden and Nicole Richie
When It Took Place: December 2010
Why It Was So Crazy: When these two got hitched, Richie wore not one, not two, but three different wedding dresses on her big day. The ceremony and reception, both held at Lionel Richie's estate in Beverly Hills, included more than 150 VIP guests like Khloe Kardashian, Samantha Ronson... and an elephant. Yes, an elephant. The couple also somehow managed to keep their wedding out of the press, which is a crazy accomplishment in and of itself.
