The 22-year-old channelled old Hollywood as she stepped onto stage, glammed up from head-to-toe in a glittering cream-hued dress and long, white gloves.

Walking onto stage from behind a deep red curtain, Ariana got the performance started with a sultry and sexy rendition of her brand new song Focus.

Ariana then returned back onto stage and retreated behind the red curtains, but quickly popped back into the spotlight, now donning a skimpier and sexier beaded one-piece.
