Country stars are stepping up to fight hunger this year through WhyHunger's Hungerthon auction. Kenny Chesney has donated a fly away trip for one lucky bidder and a friend to meet him on his No Shoes Nation tour. So far, that item has fetched more than $13,000.

Zac Brown Band has also donated an eat-and-greet experience at one of their 2013 concerts.  That's going for around $3,000.

Brad Paisley , Taylor Swift , Carrie Underwood and Jason Aldean also have items up for bid in the auction, which ends this afternoon. Check it out at CharityBuzz.com/Hungerthon .
