Cameron Diaz was helped through the grieving process by her young co-stars.

The actress - who lost her father Emilio in April 2008 after he died of pneumonia while she was shooting the film 'My Sister's Keeper' - said it was the kind words of Abigail Breslin, 13, and Sofia Vassilieva, 17, who provided the most comfort.
