Justin Bieber's first live performance of "Boyfriend"! Hey there, I'm Karli Bulnes. See the pop star take the stage on The Voice finale and hear the cast's kind words about him in today's PopSugar Rush. Justin Bieber wore his gold sneakers to sing his hit "Boyfriend" for the first time in front of an audience on Tuesday's finale of The Voice. Backstage with us, host Carson Daly was quick to commend the 18-year-old star for keeping his promise to perform after giving a sneak peek of his music video on the show a few weeks earlier. "He's great, he's a man of his word, he was a boy of his word, now he's a man of his word, he promised to come back and do the performance and he did it, excellent." Justin's exciting appearance was one of several memorable moments from the evening, which included former Alicia Keys backup singer Jermaine Paul claiming the crown for Team Blake Shelton. "Jermaine won the grand prize and he told us who the first phone call he got was from, Alicia Keys!" "Yeah it felt great just knowing she had watched this whole thing, she's actually known me for a very long time even before backgrounds, God is good." "In the end one of my favorite won and it was Jermaine, I'm really happy for him, Blake is so ecstatic, I love the smile on his face, he worked so hard on this." Ever since friend and fellow judge Adam Levine won season one, Blake's been trying his best with his artists to win, and he told us he felt like a Bieber fanatic after claiming the victory. "I always wondered what this would be like to win The Voice as a coach/I don't feel as much proud as I feel like one of those girls that was in the audience when Justin Bieber came out and everyone was screaming and they were falling apart, you know what I mean?" [While winners Blake and Adam have a definite bromance going on, a lot was made about the feuding amongst the judges this season. Cee-Lo Green told reporters on the red carpet he does think it's possible that the drama had an effect on the outcome of the show. "It was a bit of a distraction or so I've heard." Nevertheless, Cee-Lo added that all four judges get along behind the scenes and he thinks they'll all be back for season three. I'm Karli Bulnes and thanks for watching PopSugar Rush!
