Andrew Garfield and Emma Stone hold up make-shift charity signs for snappers

The Amazing Spider-Man co-stars Andrew Garfield and Emma Stone put their fame to good use when they were confronted by paparazzi on Saturday by flashing handmade signs promoting charities.

The real-life couple was eating lunch in New York City and noticed a camp of photographers gathering outside, but instead of running for cover the stars used the photo opportunity to raise awareness for a good cause.

Emerging from the eatery, Garfield and Stone held up cardboard posters in front of their faces with information about two charities they back.

The signs read, "We just found out that there were paparazzi outside the restaurant we were eating in. So?Why not take this opportunity to bring attention to organizations that need and deserve it: www.wwo.org and gildasclubnyc.org. Have a good day!"

The Worldwide Orphans Foundation, which boasts Garfield as its ambassador, assists orphans in becoming "productive members of their communities and the world," while Stone volunteers for cancer support network Gilda's Club NYC, named after her comedy hero Gilda Radner, who died from ovarian cancer in 1989.
