Sandra Bullock

Bryan Randall died aged 57 after being diagnosed three years ago with amyotrophic lateral sclerosis (ALS).

In a statement, Randall's family said they were "immensely grateful to the tireless doctors who navigated the landscape of this illness".

Bullock was also praised for her care by her sister Gesine Bullock-Brado in a tribute she posted on Instagram.

"ALS is a cruel disease," she wrote, "but there is some comfort in knowing he had the best of caretakers in my amazing sister and the band of nurses she assembled who helped her look after him in their home."

The world is a biased place. That's a fact Sandra Bullock isn't sugar-coating when she explains it her son, Louis. In her new cover story for Glamour, Sandra says she "absolutely" discusses racism with her son, whom she adopted in New Orleans after Hurricane Katrina. "It's an open conversation we have. He fully understands what that means.

The 46-year-old reality star split with Bullock in April 2010, after several women claimed to have affairs with him while he was still married to the 51-year-old Oscar winner. James issued a public apology to Bullock at the time, stating, "There is only one person to blame for this whole situation, and that is me. It's because of my poor judgment that I deserve everything bad that is coming my way."
