Ariana Grande tributes Whitney Houston on 'Greatest Hits'

Ariana Grande tributed Whitney Houston during the finale of ABC’s 'Greatest Hits.' She belted out renditions of ‘How Will I Know’ and ‘The Bodyguard’ classic ‘Queen of the Night.’

There's no doubt the chick can sing, but I don't think these songs quite work with Ari's voice. Naturally, when you hear someone cover a Whitney song, you're going to compare it to the original and it will never come close (although Deborah Cox and Alexandra Burke can deliver a similar soul element, which Ari lacks). Ariana's diction still needs work, and so does her stage presence.
