While on a break between contestant performances, the singer beamed when she was handed her baby boy. Holding her son up so the cheering audience could see him, Shakira then sat back down in her red chair, cradling her babe while their picture was taken.
The show's host, Carson Daly (also a dad
), went right over and starting 'oohing' and 'ahhing' at Shakira's little guy, while coaches Blake Shelton
and Adam Levine took quick peeks before returning to their seats.
