The 89-year-old showbiz patriarch is currently in the final stages of terminal cancer, and Paris has revealed that she and the other members of her world-famous family have gathered around Joe.
Paris - who is the daughter of the late pop star Michael Jackson - wrote on Twitter: ''blessed to have a family that comes together the way the Jacksons do. (sic)''
In a later tweet, Paris responded to a fan message that urged her to go and visit her granddad.
The 20-year-old model said: ''we all have. i flew out this morning to be with him all afternoon and evening.''
During the same series of tweets, Paris also revealed that a recent tweet attributed to Joe hadn't actually been written by the legendary talent manager.
The original message, which was sent from Joe's official account, read: ''I have seen more sunsets than I have left to see. The sun rises when the time comes and whether you like it or not the sun sets when the time comes.''
But Paris has now confirmed the message was not written by her grandparent, as many fans had initially believed.
She explained: ''this is a beautiful tweet. though it upsets me to see whoever is in charge of this account taking advantage of it. my grandfather did not tweet this. i'm not sure if he's ever used this account. (sic)''
The father-of-eleven - who suffers from diabetes and is also believed to have a form of dementia - suffered a stroke in Brazil in 2015 which left him temporarily blind.
Joe was also involved in a car accident back in 2017 and has reportedly suffered at least one heart attack in recent years.
