Ariana Grande's performance duet with Xtina underwhelms

On paper, this should have been good. But in reality, Ariana and Christina's performance was such a hot mess. Christina's voice simply didn't fit with ‘Dangerous Woman’ and they were both just screaming high notes. Very underwhelming to say the least. They also performed Ari's latest single ‘Into You’ during last night's ‘The Voice’ finale.
