Everything you need to know about Justin Bieber's Live Lounge performance
And here's how the set shaped up. Yep, that's JB's handwriting.
Biebs treated us to five awesome-sounding songs, which began with What Do You Mean? And it sounded perfect.
Let Me Love You followed and Justin was already wowing everyone.
Then came a superb performance of Tracy Chapman's Fast Car.
Then he ACTUALLY COVERED 2PAC, which was pretty great.
Justin then gave us a taste of his current UK number 1 single, Cold Water, and it sounded SO GOOD.
He finished his five-song set off with Love Yourself. Sadly, it ended there but we just wanted MORE MORE MORE BIEBER.
Fans seemed to LOVE the performance...
Others were suitably impressed...
Oh, and one other thing - only flippin' Usher was there too. He's performing for Live Lounge Month tomorrow, FYI.
After Justin's set, he took to Twitter to share just how nervous he was, but we reckon he did AMAZINGLY! You can check out the full video of his performance soon!
