Diana Ross has commandeered the planning for her son Evan's wedding to Ashlee Simpson.
The Enquirer reported that Diana has completely cut Ashlee out of the planning, and will even wear an ivory-colored gown that will put Ashlee's dress to shame.
"Diana is already proving to be a monster-in-law," an insider said.
Diane, who insisted that Ashlee "call her Miss Ross," demands that the wedding be held at her Connecticut home even though Ashlee wants to have it in Hawaii or California.
Having the wedding at her home isn't good enough for Diana, however. She also plans on singing excessively throughout the ceremony and reception.
Diana refuses to have a Vegan wedding cake, despite Ashlee's desperate pleas.
