Nicole Richie planning small wedding

Socialite Nicole Richie is planning a small wedding, cutting many old pals, including Paris Hilton, from the guest list.

Richie will wed rocker Joel Madden on Saturday at her dad Lionel Richie”s Beverly Hills estate.

Nicole, said to be wearing a Marchesa dress, is planning an intimate affair with guests including Samantha Ronson and Christina Aguilera.

“Nicole”s wedding will be super small, and a lot of people who have played a role in her life like Paris have been cut from the guest list,” the New York Post quoted a source as saying.

“She”s keeping the dress a secret and hasn”t even told her bridesmaids who the designer is.

“Christina, who ironically is going through a divorce, will be performing a song. She has been a good friend and wants to be there for Nicole,” the source added.

A rep for Hilton, who”s busy filming a reality show, declined to comment on the report.
