Justin Bieber celebrated his first GRAMMYs win with some high-energy dance moves!
After bringing his adorable little brother to the red carpet, the 21-year-old singer stepped into the spotlight during music's biggest night and wowed the crowd with a two-part performance -- complete with a bizarre guitar toss.
Bieber kicked off his set with an acoustic rendition of his hit single "Love Yourself." Wearing a backwards black baseball cap and a cheetah-print jacket, the slowed-down song sounded almost unrecognizable (in a good way!) as he crooned to the audience.
Before moving onto his next song, the Biebs belted out the final note of his catchy ballad and then ditched his guitar by slamming it to the ground.
After the instrument fling, Bieber sprinted from the audience platform to the mainstage where he joined Skrillex and Diplo for a high energy version of "Where Are Ü Now."
The "Sorry" singer eventually ditched his jacket -- opting for a black tank top instead -- and gave us some serious Snoopy from Charlie Brown vibes with his high-kicking dance moves.
ET caught up with Bieber's ex-girlfriend Selena Gomez earlier in the night. Press play on the video below to find out that she had to say about his very first GRAMMYs win!
