Justin Bieber went rock when he performed at the 2016 Grammy Awards on Monday, February 15. The Canadian heartthrob turned one of his hits, "Where Are U Now", into a rock song with the help of his collaborators Skrillex and Diplo.

Bieber started his set with an acoustic rendition of "Love Yourself". Clad in a leopard-print jacket, he sang while playing his guitar which he slammed on the floor before he launched into "Where Are U Now" with some violinists and a band that included Skrillex on electric guitar and Diplo on drums.

The Weeknd, Tori Kelly and Kendrick Lamar were among other performers taking the stage that night. The Canadian R&B star first played a portion of his hit "Can't Feel My Face" before delivering a stripped down version of "In the Night" accompanied by a pianist and a cello player.

The Weeknd was supposed to be joined onstage by Lauryn Hill during his set. The former The Fugees member, however, failed to show up at the event because of traffic, according to Hill's representative.

"The Grammys announced a performance by Ms. Lauryn Hill prematurely and without approval. Ms. Hill had concerts all weekend, leaving no time to prepare, and was uncertain she would even be able to make it to L.A. in time to rehearse for the event," the rep wrote in a statement. "The performance was intended to be a surprise and unfortunately, due to its last-minute nature, was unable to come to fruition."

Tori Kelly, meanwhile, teamed up with fellow Best New Artist nominee James Bay for a mash-up of their respective hit singles, "Hollow" and "Let It Go". They were backed by nothing but the acoustic guitars they played themselves.

Kendrick Lamar delivered another interesting performance that night with a couple of his "To Pimp a Butterfly" tracks. Along with some dancers who emerged on the stage in chains and prison uniforms, the rapper began spitting "The Blacker the Berry". He continued with "Alright" as he moved to another stage where some African dancers surrounded a raging bonfire.

The 2016 Grammy Awards aired live on CBS from the Staples Center in Los Angeles. Taylor Swift kicked off the annual prize-giving event with her latest "1989" single, "Out of the Woods". Despite some technical glitches, Adele still managed to wow fans with "All I Ask".

Lady GaGa was also part of Music's Biggest Night as she channeled David Bowie when performing a tribute to the late musician. Meanwhile, Rihanna who was set to perform her "Anti" song "Kiss It Better" had to cancel her appearance due to an illness.
