We all know Ariana Grande's a huge Britney fan, and once again she's channeling the Pop Princess in the music video for her latest single off My Everything. 'Problem' saw her tackling 'Oops!...I Did It Again' and now she's trying to make her own apocalyptic stunner à la 'Till the World Ends'.

'One Last Time' is a wise choice for her next single, giving us something more upbeat after 'Love Me Harder'. In the video, we follow Ariana from the vantage point of her boyfriend as the pair flee through the streets of L.A. as the end of days sets in.

Through some fighting and refusal to listen to the cops, Ariana and her (rather cute) boy toy arrive at the top of a building where they stand looking at the crashing of the heavens before moving into a loving embrace.

Although I love me some Ariana, she didn't pull off the Britney very well here, and the video feels like an afterthought. It's really not up to par with the rest of her work and I feel disappointed. Maybe she's too busy learning Hiragana.
