JAKE OWEN'S Twitter generosity came out to shine again last week.  A fan named LeAnn Chapman couldn't get tickets to his show in Chicago . . . so she hit up Twitter to voice her frustration. 

She wrote, "Crushed that @jakeowen in Chicago is sold out."

Jake noticed in LeAnn's profile summary that she's a Gold Star Wife . . . so he jumped on her request.  He wrote back, quote, "I'm leaving you four tix.  I'm proud to do it.  Your husband is a hero.". love ya, Jake!!!!
