Poor Jennifer Aniston.

A new report just claimed that the actress is very worried about her dad, John Aniston's current health status.

“John is way less mobile than he used to be, and Jen’s concerned about him. He spends most of his time outside of Los Angeles these days and that means Jen finds it difficult to see him because of her busy schedule,” a source told Radar.

“Jen’s tried inviting John to stay with her and her husband [Justin Theroux] in LA, but he’s not in a position to travel much so she has to make do largely with phone calls.”

This comes on the heels of Jen losing her estranged mother, Nancy Dow, back in May — however her relationship with the opera singer is much different.

“She wants to spend Thanksgiving and Christmas with her dad," the insider added. "She adores him and is desperate to treasure every last moment they have together.”
