Following reports the Joe Jackson suffered a stroke that left him blinded, Paris is reportedly devastated.
The only daughter of the King of Pop is reportedly having a hard time accepting the situation after having to loss Michael Jackson at an early age.
"For Paris, Prince and Blanket, the possibility of losing Joe right now is horrific," the insider told Radar Online. "Paris is finally doing well and has overcome so much, but she is still very, very fragile."
Joe, who is celebrating his 87th birthday in Brazil suffered a stroke was rushed to the intensive care unit in a San Paulo hospital.
While in the hospital, Joe suffered three heart attacks and is now reportedly "on the verge of death."
"Paris is Joe's baby and she is his heart. She is the youngest of the female Jacksons and she is super close with her granddaddy," the source of InTouch Weekly continued.
Following the death of Michael Jackson, Joe reportedly helped the three kids as he became their "father figure."
"Everyone is really worried about him because it seems he is not handling Michael's death easily already, so one can only imagine how he would handle Joe's death."
But while everyone in the family are worried, Michael's eldest child, Prince is reportedly busy partying.
Radar Online reported that Prince Jackson has continued to disappoint the family as he was seen partying during a sad moment in the family's life.
Apparenlty, Prince and his cousins Jermajesty and Jaafa have chosen to party on a yacht in Miami instead of being on their grandfather's side.
"Prince has always been the irresponsible and selfish one among the children," the insider told the publication.
Adding, "While the other kids are stressed about Joe's health, Prince is more concerned with having leisure time and enjoying himself."
The kids' grandmother, Katherine Jackson, is reportedly saddened by Prince's behaviour.
"Katherine is consistently disappointed by Prince's behavior, but Prince disappearing during this time comes as no surprise to anyone."
Adding, "Prince and Jermajesty are nothing but trouble when they get together and they are a bad influence on each other," said the source.
"But the family much prefers them to at least be together because the family bond is so important to them all, including Joe."
And like Katherine, Paris is reportedly very dismayed with his brother. In fact, Radar Online previously reported that the two are not even talking.
"She cannot tolerate her brother and says that he is disgracing their father's legacy," the publication said of the feud. "The family is doing everything that they can to keep Paris away from Prince because they do not want her to go down the wrong path again."
