Justin Bieber wishes fans would ''respect him'' when asking for photos.

The 'What Do You Mean?' hitmaker went on a rant on Snapchat about being bombarded for selfies while out and about.

In a series of videos, Justin can be heard saying: ''The way you ask or approach me when you want a photo with me is going determine if I take a photo or not.

''If I'm walking somewhere or arriving somewhere and you guys are asking me to take a photo, if I don't respond, if I continue to keep walking, the likelihood is that I probably don't want to take a photo at that moment.

''If you start screaming louder that's not going to make me take a photo more.''

The 21-year-old star continued to speak out to fans, insisting he is happy to take pictures with fans, but only if they are polite, and hopes his loyal Beliebers will be understanding if he can't always accommodate snaps.

He added: ''I want to enjoy the moment like you're enjoying the moment but I can't enjoy it if I'm not feeling there's any respect given to me that moment.

''Usually the chances are I'll take a photo but if perhaps I don't, or I'm not in the mood to take a photo that moment, please just respect me and just treat me the way you want to be treated.''

Justin further questioned whether fans who bombard him in the streets are there ''to see me in the first place'' or ''so you could tell people about it?''

The singer concluded: ''Just remember I'm not unattainable, unreachable, I'm just like you and I communicate just like you, so next time remember.''
