Jennifer Aniston has been sizzling on the red carpet, schmoozing with other A-list stars and enjoying a PDA packed love fest with new beau Justin Theroux, but one place she hasn’t been is by her mother’s side.

Nancy Dow, Jen’s 75-year-old mom, had a stroke a few weeks ago, and while her daughter visited her in the hospital she was not with her when she was released.

In the photo a frail looking Dow is seen leaning on a cane as she walks out of a Los Angeles pharmacy as she recovers from her long hospital stay.

Jennifer Aniston "broke down uncontrollably" at her mother's bedside after she had a stroke, RadarOnline.com is reporting.

The former Friends star -- who was estranged from her mom Nancy Dow, 75, for 12 years after she gave an interview about their relationship in 1996 -- visited her in the hospital over the weekend after she suffered a brain seizure and was overcome with emotion as soon as she saw her.

A source told the Daily Mirror newspaper: "Jen headed for the Los Angeles hospital the second she heard. Nancy is desperately ill, and it is no exaggeration to say people fear the very worst.
