Read Jordana Brewster's official statement on Paul Walker's tragic death via Entertainment Weekly:

"Paul was an enormous presence in my life for the past fourteen years. While many would be satisfied with material success it made Paul more convinced of the need to help others. He never spoke of his immense generosity or philanthropic endeavors unless I prodded, however. This is what made Paul, Paul."

"He lived with integrity, humanity and humility and seemed most happy when talking about his daughter, Meadow," said Brewster.

"I don't know anyone who lived each moment more fully and loved life more than Paul; making his loss all the more heartbreaking."

On Sunday, the stunned 30-year-old actress tweeted, "Paul was pure light. I cannot believe he is gone."

Brewster worked with Walker in the "Fast & Furious" series as his romantic interest Mia Toretto. She was in the middle of shooting the upcoming "Fast & Furious 7."

Walker's co-stars have been shattered to learn the news about his death in a car accident. Reportedly, they are "too distraught" to come back to work on the set of "Fast & Furious 7" this week.

A source told TMZ, "No one wants to even think about the movie. Period."

Other sources told TMZ that Walker was slated to film important scenes for the film this week in Atlanta.
