Good Charlotte rocker Joel Madden and Nicole Richie reduce wedding guest list

The socialite ' who is expected to marry Good Charlotte rocker Joel Madden this weekend ' has reportedly upset some of her pals, who thought they would be attending the nuptials at her father Lionel Richie's Californian home.

A source said: "Nicole cut down the guest list because she didn't want a huge wedding.

"She didn't invite a bunch of her celeb friends. This has apparently upset a lot of people."

Though Nicole is not at her father's home overseeing preparations for her big day ' which have included the construction of a dance floor over the outdoor pool ' friends insist the ceremony and reception will reflect her tastes.

The source told RadarOnline.com: "Nicole is going for a vintage and romantic vibe. The wedding will be true to Nicole's style.

"Christmas has always been about family and faith for Nicole and Joel, so there is no better time of the year for them to wed."

Nicole, 29, is believed to have asked her friend Christina Aguilera to sing at the wedding, while Joel ' who has children Harlow, two, and 14-month-old Sparrow with the fashion designer ' will have twin brother Benji at his side as Best Man.
