As reported by RadarOnline, Jennifer endured a famously fractured relationship with her actress mum, Nancy Dow.
The mother and daughter did not speak for ten years before Jen's divorce from Brad Pitt.
The Dumplin' star previously admitted of Dow: "I did not come out the model child she'd hoped for."
In 2017 RadarOnline reported that court documents showed Aniston's mother had written her out of her will.
Melick, on the other hand, enjoyed a close bond with her grandmother.
The 22-year-old Navy medic - who is the daughter of Aniston's half brother - looks to be splashing her inheritance on a lavish lifestyle which has seen her take trips to the Grand Canyon, New Orleans, Miami, New York and Santorini, Greece since the beginning of 2019 alone.
