Who would’ve thought that YouTube sensation Tori Kelly would someday perform in front of thousands of people at a popular awards show and share a stage with acclaimed tenor Andrea Bocelli?

The young singer-songwriter, who slowly rose to fame after posting numerous singing videos on YouTube, brought the house down at the 2015 MTV Europe Music Awards or EMAs. The annual event was held on October 25^th at the Mediolanum Forum in Milan.

Kelly appeared on stage in an all-gold number and proceeded to perform her hit song, “Should’ve Been Us,” the second single off her debut album, Unbreakable Smile.

At the bridge of the song, however, the audience was treated to a surprise when Kelly suddenly launched into a ‘90s medley of sorts – starting off with TLC’s female anthem, “No Scrubs” and following up with the Fugees hit, “Ready Or Not.”

Kelly wrapped up her performance beautifully by going back to her own song and bowing to the pumped up crowd. As if her song number wasn’t enough to showcase her vocal prowess, Kelly turned over the spotlight to the Italian classical singer, who belted out his own song, “Por Ti Volare.” After Bocelli’s aria, he and Kelly did a duet, performing the 2013 hit “Just Give Me A Reason” by Pink and Nate Ruess.

That was breathtaking!

The unlikely pairing yielded a unique rendition of the popular song, which garnered loud applause from the audience and a standing ovation, no less.

Kelly is not the first pop singer that Bocelli has collaborated with. He has released songs and albums with such singers as Ariana Grande, Mary J. Blige, and Celine Dion to name a few.
