Sandra Bullock is proving to be one generous actress.
The Oscar winner donated $1 million to the American Red Cross this week to aid earthquake and tsunami victims in Japan, the charity told CNN on Thursday.
This is the largest celebrity donation to the Red Cross since the disaster, although the charity has received other anonymous donations, it reports.
