Brother of Nancy Motes’ Fiance Claims She Was “Driven to Take Her Life” By “Cruelty” of Julia Roberts

In shocking new claims, the brother of Nancy Motes‘ fiance is pointing the finger of blame in her tragic passing directly at Julia Roberts.

Conner Dilbeck, whose brother John was engaged to Nancy, the Oscar-winner’s half-sister who died of an apparent drug overdose Sunday, took to his Facebook page to express his grief and anger, even going so far as to allege the 37-year-old former Glee production assistant committed suicide because of the siblings’ longstanding rift.

Read his full message below:

“I am posting this as a plea to everyone to Prey [sic] for my Brother John. His lovely Fiancé, Nancy Motes, was driven to Take her Life yesterday because of the Pure Cruelty of her Sister, Julia Roberts (yes Ms. Pretty Woman herself), that has done everything in her power to Ruin her and my brothers lives,” he posted alongside a photo of his brother proposing to Nancy on the set of the hit FOX show.

“He is overwhelmed by this horrible event and all the Turmoil Julia has subjected them too,” he added.

According to the New York Daily News Tuesday, Nancy was discovered in a bathtub while housesitting and left behind a five-page suicide note detailing the turbulent relationship between the siblings.

“There were three pages of rantings that her sister drove her to do this,” a source told the Daily News. “There was one page to her mom, telling her how much she loved her, and one page apologizing to (her fiancé John Dilbeck).”

The relationship between Nancy and Julia, whose brother is actor Eric Roberts and mother is Betty Lou, began to deteriorate when Nancy gave an in-depth interview in May 2013 describing her ongoing depression over her weight issues, gastric bypass surgery, struggling acting career, and how her famous sister bullied her over her looks.

Since then, Conner has posted a clarification, stating there are “8 pages to the Suicide letter not 5. I was told that Nancy wanted the Truth to come out,” he wrote.

But despite the bad blood, she was hopeful of a reconciliation: “I think we’re both trying to change our opinions of each other,” Nancy told the NYDN last summer. “It’s a work in progress. It’s not going to be fixed overnight.

“My family, we love each other absolutely. I love Julia absolutely, and I have no doubt she loves me.”

But in the few months before her death, she ranted via Twitter seemingly about the 46-year-old movie star, even calling her a “b***h.” (The tweets have since been taken down, but were captured by the Daily Mail.)

In the wake of the family’s sudden loss, Julia canceled her scheduled public engagements, including the Academy Awards Nominees Luncheon in Beverly Hills Monday and a Jimmy Kimmel Live appearance later that day.

No official cause of death has been released and Julia has not commented about the reports. However, the family issued this statement: “It is with deep sadness that the family of Nancy Motes … confirms that she was found dead in Los Angeles yesterday [Sunday] of an apparent drug overdose,” the statement reads. “There is no official report from the Coroner’s office yet. The family is both shocked and devastated.”
