Cameron Diaz is spotted on the set of Gambit in London earlier this week (July 19). Colin Firth was also seen on set - check out the pics in the gallery below.
Cameron is just a few years away from turning 40, but she told Australia's Cleo magazine that there's nothing to be feared:
"There's nothing scary about it at all. Life is so much better as you get older. You're liberated from so many things. I feel stronger, better, more capable, more fulfilled, and happier than I ever did when I was 29, when I was 30, even 35. I prefer it."
