It depends. Justin bieber himself says he will go out with a प्रशंसक if he falls in love. But आप hav 2: 1. Know Him 2. Seen him up close But he might be really busy with concerts and he is constantly moving to do concerts at other places so आप might have a 1 in a million chances to go out with him. :D sah-rry but its the truth
HAHA no. Justin Bieber has a girlfriend. And I bet he doesn't even know आप exist(no offense), as well as all the other million fangirls that want to marry him.
