Nicole Richie, Joel Madden wedding draws family, friends – and an elephant!

Talk about a surprise guest.

After two children and four years together, Nicole Richie and Joel Madden invited about 130 close family and friends for their scheduled wedding Saturday.

But one attendee stood way out: a trained elephant was spotted being led into the Los Angeles estate of Richie's father, music superstar Lionel Richie, where two tents were set up for the ceremony on a warm evening.

Otherwise, the couple appeared to be sticking to tradition.

"They wanted an Old Hollywood, glamorous feel to their wedding," says another source. "They're going all-out with the decor. Nicole wanted a memorable, elegant affair for only their closest friends and family on their special day."
