Blake Shelton, 45, looked like a happily married man during his latest performance in front of a cheering crowd! The country singer was in the middle of singing “Happy Anywhere” during the first night of CMA’s Summer Jam concert in Nashville, TN on July 27 when he was joined by his wife Gwen Stefani, 51. About halfway through their incredible duet on stage, the new husband excitingly introduced the No Doubt crooner as “Gwen Stefani Shelton,” which made the fans cheer even louder.
