Julia Roberts’ mother, Betty Lou Bredemus, has passed away at the age of 80 after a battle with lung cancer.

Bredemus died in Los Angeles on Thursday, where Roberts was filming The Secret In Their Eyes.

She is survived by three of her four children; Eric Roberts, 58, Julia Roberts, 47 and Lisa Gillan, 49. Her daughter, Nancy Motes – who was Julia’s half-sister- committed suicide at the age of 37 last year.

People reports Bredemus also leaves behind four grandchildren; Julia’s twins Phinnaeus and Hazel, 10, and son Henry, 7, and Eric’s daughter, American Horror Story actress Emma Roberts, 24.

InTouch reports she died at Saint John’s Health Center in Santa Monica.

She was reportedly living with the Pretty Woman star at her home though she did have her own home nearby.

Bredemus was reportedly diagnosed with cancer in 2013. The Oscar winner’s father, Walter Grady Roberts, died of cancer when she was just 10.
