She is routinely seen with her long locks up in her signature ponytail.

But Ariana Grande ditched her trademark hairdo and let her tresses fall down in romantic curls as she performed her new song Focus for the first time on television at the American Music Awards on Sunday. 

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.
