Julia Roberts' half-sister Nancy Motes, who passed away recently, had called her a "bitch" on Twitter just days before she died from a suspected overdose.
Motes wrote, "Just so you all know 'America's Sweetheart' is a B**CH" in an attempt to defame the 46-year-old American actress and added, "Do you want to be a fan of someone so cruel? She's not even that good of an actress", the Mirror reported.
The 37-year-old daughter of Betty Lou and Michael Motes had accused her family of abandoning her and had expressed her anger on the micro-blogging site.
Motes' body was discovered in the bathroom of her Malibu home by her fiance and her family had express their sadness over her death due to "an apparent drug overdose".
