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. Richie wore a wedding dress by Marchesa, and their rings were by jeweler Neil Lane, who also crafted Richie's 4-carat engagement ring, sources tell PEOPLE.
"They're going all-out with the decor." says another source. "Nicole wanted a memorable, elegant affair for only their closest friends and family on their special day."
How the elephant fit in wasn't immediately known.
Guests included the groom's twin brother and Good Charlotte bandmate Benji Madden, 31, Sam Ronson, as well as Gwen Stefani and Gavin Rossdale.
Richie, 29 and Madden, 31, announced their engagement in February, and Richie's friends threw her a luxurious bachelorette party in Mexico in September.
