Bieby proved just how sweet he can be during his Moscow concert last night when he whisked a little girl up on the stage to serenade her in front of 80,000 VERY jealous fans.
The girl was SO overwhelmed with joy as JB sang the classic hit, Baby, that she broke down into tears!!!
Now this is the kind cutie we know and love!!!
Ch-ch-check out the heartwarming moment (above)!!!
We guarantee it'll make you belieb all over again!!
