audience members at the show's battle round taping on Tuesday evening in Burbank, Calif., when she showed off her new son, Milan, born in January
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.

But just before the break, the 2½-month-old started to fuss – loud enough that his little cries echoed through the whole studio. After the crowd let out a cute 'aww,' Shakira handed her baby off to be taken backstage – but not before puffing out her bottom lip in protest. – Jessica Herndon
