Cameron Diaz showed off her generous side on the set of new film The Other Woman just before the shoot wrapped earlier this month (Aug13) by treating cast and crew to a fast food picnic.

The actress reportedly paid $1,000 (Gbp6,670) for a MCDonald's feast to thank her co-stars, like Leslie Mann and Kate Upton, and crew pals for working around the clock to complete the movie.

A source tells In Touch magazine, "Everyone was there working hard to finish up the final scenes and they were famished, so Cameron gave her assistant $1,000 in cash and had her make a run to MCDonald’s.

"It was like a big picnic - so much fun. Everyone was really grateful."
