Why 'Showtime' hosts questioned live vocals of Morissette

"The Voice of the Philippines" finalist Morissette Amon wowed the "It's Showtime" audience on Thursday with a sing-and-dance number that had the hosts questioning whether her vocals were live.

After her opening performance of Ariana Grande's "Break Free," Amon was asked by Vice Ganda, Anne Curtis and Vhong Navarro whether she was indeed performing live, and not lip-synching.

The hosts commented that Amon's vocals did not falter despite dancing non-stop and moving from one side of the stage to another. Amon confirmed that she was singing live, but was "struggling" to keep heavy breathing unnoticeable.
