"It is with deep sadness that the family of Nancy Motes ... confirms that she was found dead in Los Angeles yesterday of an apparent drug overdose," the family said in a statement released on Monday.
"There is no official report from the Coroner's office yet. The family is both shocked and devastated."
"When I was in high school and she was an adult, she would just let me know that I was definitely overweight," Motes told the NY Daily News last year.
“She would make it quite clear to me and in a not-so-nice a manner.”
Motes described herself as an “awkward” who was bullied in school. She said she was intimidated by her “very pretty and very popular” sister.
“I think that growing up as Pretty Woman’s little sister has definitely made me try to see the person inside and not the person outside," she said. "A lot of my life I felt judged for my weight.”
But Motes found love and was planning to marry John Dilbeck, much to Julia's dismay.
Julia, 46, planned to boycott the nuptials because she doesn’t like the groom and doesn’t want to get stuck paying for the wedding.
“Julia doesn’t think much of Nancy’s husband-to-be,” an insider said. “She’s convinced he’s sponging off Nancy, who doesn’t have much money in the first place.”
