Nicole Richie, Madden tie the knot

New York: Socialite Nicole Richie has tied the knot with rocker Joel Madden in a simple ceremony.

They got married in a traditional ceremony Saturday. The couple, who had been dating for the past four years and have two children together, invited about 130 guests including family and friends. Madden`s twin brother and Good Charlotte bandmate Benji Madden were among them.

Richie`s father and music superstar Lionel Richie set up two tents for the ceremony.

"They wanted an Old Hollywood, glamorous feel to their wedding," quoted a source as saying. "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."
