Backed by his Tennessee Kids band, Justin sang in his incomparable falsetto, shimmied across the stage like an old school pop idol, giving Suit & Tie a Rat Pack feel by calling Jay-Z out of the audience for the rapper's verse.
Whether in black and white or colour, JT brought down the house and also gave fans a glimpse of what to expect from his third solo LP The 20/20 Experience by singing new track Pusher Love Girl.
Taylor Swiftalso put on an impressive display surrounded by aerialists, ballerinas, fire dancers and a stage full of circus performers as she acted as the ringleader to open the ceremony in grand style, by mixing a surreal circus with a bit of Alice in Wonderland magic.
Dressed all in while, Swift made sure to pull out all the stops to help get the night off the launch pad. Her mind-bending performance of We Are Never Ever Getting Back Together featured a wayward lover strapped to a spinning wheel.
During her performance, the 23-year old joked: "So, he calls me and says, 'I still love you.' And I'm like, 'I'm sorry, I'm busy opening up the Grammys and we are never, ever getting back together. Like ever'."
Carrie Underwoodmay have had that cool CGI dress, but Frank Ocean really burned out optic nerves with a trippy performance that made it look like he was running to stand still.
Wearing his signature headband, Frank stood behind a waist-high keyboard surrounded by a white screen for a meditative Forrest Gump.
While a movie of his churning legs running down a secluded desert highway screened below his torso, Ocean crooned the meditative tune flawlessly. Plus, he threw in a sweet whistling solo as he turned to leave the stage.
