Nicole Richie Ties the Knot!

130 of Nicole Richie and Joel Madden's closest family and friends — and a trained elephant — watched the couple tie the knot yesterday at Nicole's adopted father, Lionel Richie's Los Angeles estate. 

Gwen Stefani, Gavin Rosdale and Samantha Romson were also on hand to watch Richie walk down the aisle in a dress by Marchesa

Richie, 29 and Madden, 31, got engaged in February. 

The bride has yet to explain why she invited an elephant to the lavish ceremony. Maybe Nicole just wanted to upstage JoAnna Garcia, who got married at the same time yesterday on the east coast.
