Motes was the half sibling of Julia Roberts and her brother Eric. She was the daughter of their mother, Betty Lou, and Michael Motes was her father, while Walter Grady Roberts, who passed away, had the role of dad for Julia and Eric.
Julia Roberts and Nancy Motes both chose acting as each woman's profession but the "August: Osage County" thespian obviously has had a higher profile in her long career than her younger sibling.
By way of background, Motes suffered from obesity and so underwent gastric bypass surgery in 2013.
A lot of the reason for this was delivered by Nancy who said, "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. A lot of my life I felt judged for my weight."
Even though she lost a lot of weight after the operation, she still struggled but she also thrived. She worked on "Glee"as a production assistant on Glee and was making plans to marry her fiance John Dilbeck this coming spring.
And now that is not an option because Julia Roberts' sister Nancy Motes is dead of an apparent overdose at age 37. Come back for updates since complete details are not yet available as this sad news breaks.
