Nicole Richie, Joel Madden Tie the Knot

After four years and two kids together, Nicole Richie and Joel Madden have officially settled down. The couple got married in Los Angeles on Saturday in front of 130 guests.

"They're going all-out with the decor," a source told People. "Nicole wanted a memorable, elegant affair for only their closest friends and family on their special day."

Part of that decor included a trained elephant, which was spotted being brought out to Lionel Richie's estate, where the wedding was held. Guests included the groom's twin and fellow Good Charlotte bandmate, Benji Madden, as well as Samantha Ronson, Gwen Stefani and Gavin Rossdale. —ISHITA SINGH
