The comedian was working on the 2009 comedy when his wife, Tran Jeong, was receiving chemotherapy treatment, and he admits he needed people like Cooper to lean on.
During a break from the production, Cooper offered to drive his co-star back to Los Angeles from Las Vegas so Ken could be by his wife's side, and when Bradley learned Tran was too weak to travel out of L.A. he invited the couple to join him at his home for a mini-vacation.
"Bradley had us come over to his place and be with his family," Jeong tells Access Live. "It got me through the most difficult period of my life."
Tran has since made a full recovery.
