Sandra Bullock's partner Bryan Randall dies after 3-year bat

Sandra Bullock's partner Bryan Randall has died.

A rep for the actress confirmed to ABC News that Randall died Saturday following a three-year battle with ALS, or amyotrophic lateral sclerosis.

"Bryan chose to keep his journey with ALS private and those of us who cared for him did our best to honor his request," Randall's family said in a statement. "We are immensely grateful to the tireless doctors who navigated the landscape of this illness with us and to the astounding nurses who became our roommates, often sacrificing their own families to be with ours."
