Justin Bieber was flew to an Airport in Atlanta and he ended up meeting Usher there
I forget were but he was walking and saw him and asked him if he wanted him to sing for him he ended up not singing to him but usher talked to his manager and got to fly back were he saw him and sang for him he had been looking up to usher his whole life
Well justin met him I don't know... Um... Let's just say he sucks and doesn't deserve to sing with him
Because he is just like that and magically and can poof anybody in front of him if he wants to sing to them. Man I wish I could. Do that . Not the singing part. Nah, I'm just playin. But I don't really know how y don't you ask him
He was in jarmaine free studios carpark when usher pulled up outside in a black car and justin went running up and said "I'm one of your biggest fans can I sing one of your songs to you?" so they went into the studio and justin sung for usher..
