Justin Bieber loves the fact his fans live by his ''never say never'' saying.

The 'Boyfriend' hitmaker - who has a song and a concert film called 'Never Say Never' - is often preaching to his supporters that they should always strive for what they believe in, and he is delighted to see that they are ''so persistent'' and ''never give up''.

The 18-year-old singer - who refers to his fans as Beliebers - said: ''The best thing about my Beliebers is they're just so persistent and they don't give up and that's what I love.

''That's what my message is, 'never say never' and so the fact they live by that and never give up, I love that.

''I would just tell them to believe in themselves, you know, in their dreams and believe in general. I think that they should just believe.''

Justin - who has 23.3 million followers on twitter - still gets shocked when he hears that some of his Beliebers have got tattoos of his name, but he thinks of his fans as the best in the world.

He told MTV News: ''There's some Beliebers, they get tattoos of my name and stuff like the other day there was a girl got a Tattoo of my name on her side.''

''On a scale of 1 to 10, my Beliebers, they're a 10 for sure I mean, yeah I can't give them anything less.''
