Ariana Grande [1] opened the Billboard Music Awards [2] with a performance of "No Tears Left to Cry" [3] straight out of a dream. The singer rocked a black minidress with thigh-high boots, but it was her hair that had us in a trance. Ariana accessorised her platinum blonde ponytail [4] with an oversize black hair bow that went all the way down her back. Is Ariana making a case for hair bows to become the new It accessory? We have a feeling the answer might be yes, especially because she rocked a very similar gold bow [5] at the Met Gala. That wasn't the only thing the 24-year-old switched up about her look — Ariana ditched her signature nude lip [6] for a pop of red. Overall, it worked like a charm!
