Country singer Scotty Mccreery is urging American teenagers to help him stamp out hunger across the country by launching food collection drives.

The former American Idol champion has teamed up with staff at the DoSomething.org charity and supermarket chain Walmart for the first-ever Peanut Butter & Jam Slam to collect one of the top requested items at food banks - peanut butter.

MCCreery has appeared in a Public Service Announcement (Psa) to encourage youngsters to hoard un-opened jars of peanut butter and jelly (jam) from friends and family and donate them to their local food bank, which will distribute the items to those in need.

In the video, he says, "Millions of kids experience hunger every day, but it just doesn't have to be this way. That's why I am lending my voice to help motivate teens to collect jars of peanut butter and jelly to help fight hunger."

The campaign was launched on 2 April (13), America's National Peanut Butter and Jelly Day, and aims to collect as much food as possible by a deadline of 14 May (13).
