Julia Roberts' half-sister, Nancy Motes called 'Pretty Woman' actress a "b*tch" on Twitter before her OD suicide

MStars has learned that Julia Roberts' half-sister called the Academy Award actress a "b*tch" on Twitter, expressing her feelings towards Roberts' in a series of tweets in January.

The tweets seem to suggest that the sisters relationship would never be repaired, before Motes died over an overdose on Sunday.

The tweets have been deleted, but according to RadarOnline, Motes said on Jan. 19, under the name @Dabbs76, "So my 'sister' said that with all her friends & fans she doesn't need anymore love. Just so you all know America's Sweetheart is a B--H!!'"

Also adding, "Do you want to be a fan of someone so cruel? She's not even that good of an actress. Happy you totally F-ed with me?"

Three days after she posted those tweets, Motes claimed that her "own family has abandoned" her that was written on Jan. 22.

A few minutes later, Motes wrote, "Hey Hag! Glad you f--ed with me yet? You're going to LOVE what's coming! FYI-You're an awful, hate filled old pathetic excuse for a human." The site also claims that this tweet was for Roberts'.

Motes final tweets included Teen Mom star Farrah Abraham, thanking her for being one of her followers, and asking, "Do you know who I'm related to?"

Motes and Roberts' shared the same mother, and had drama with the  Eat, Love, Pray actress, 46 for years.

In May 2013, RadarOnline claimed, the Enquirer reported that Roberts' planned on skipping out on Motes' wedding due to the sister drama, and thinking that Motes would only want more money.

Roberts' has pulled away from multiple engagements after the death of her half-sister, including an appearance Monday for a pre-Academy Award luncheon, and an appearance on Jimmy Kimmel.

RadarOnline also mentios that US Weekly said, the coroner's officials are going with "suicide, and not a drowning."

"The investigator at the scene listed at this point that he is going with suicide," that they were "waiting for the doctor to finish the examination. We haven't gotten anything yet."
