Los Angeles - Jennifer Aniston's mother has suffered a stroke.
The former Friends actress - who was estranged from her mother for 10 years after she gave an interview about their relationship in 1996 - rushed to be at 75 year old Nancy's hospital bedside following the incident on Saturday.
She was accompanied by her boyfriend Justin Theroux on the visit to a Los Angeles medical centre, which caused Jennifer to cry during her time there, the MailOnline reports.
Nancy is reportedly unable to speak and is in a serious condition.
Jennifer previously confirmed she and her mother - who was not invited to her wedding to Brad Pitt in 2000 - were back on speaking terms after ending the rift in 2008.
She said: "It's good. It's OK. Things are now fine between us. All of that is over, and we're in touch with one another. We speak and it's all over."
Nancy - who had Jennifer with actor John Aniston - has previously written a book about their life, entitled From Mother and Daughter to Friends.
