Nicole Richie marries Joel Madden - with elephant in attendance

Apart from friends and family, the wedding ceremony of Nicole Richie and Joel Madden witnessed an unusual guest-an elephant.

A trained elephant was spotted being led into the Los Angeles estate of Richie's father, music superstar Lionel Richie, reports People mag.

Neil Lane, who crafted Richie's 4-carat engagement ring, designed the coupe's rings too, said a source.

"They wanted an Old Hollywood, glamorous feel to their wedding. Nicole wanted a memorable, elegant affair for only their closest friends and family on their special day," said another source.

The couple tied the knot after being together for four years.
