"I was with him just four days before it happened," Gibson, 35, said on The Arsenio Hall Show. "We were on the set shooting, and that was a lot of shock and trauma for the family and all of us involved, because he's such a nice guy."
After an emotional Dec. 1 visit to the site of the crash, Gibson largely withdrew from public view, preferring instead to express his grief via social media.
"In moments like this, it feels – it feels like death has won," Gibson later posted to Facebook, paraphrasing a funeral sermon by Bishop T.D. Jakes. "But the Bible says that love is stronger than death."
