Justin Bieber has insisted "I'm a good person" and told his critics "be careful of the judgment you pass".
The singer, who has faced a barrage of negative publicity since keeping his audience waiting for a concert at the O2, told fans that he will not be brought down.
He wrote on Twitter: "Rumours, rumours and more rumours. Nothing more nothing less. Might talk about them one day. Right now I'm just gonna be positive. Can't bring me down.
"I'm focused on the good things in life. I'm blessed and not forgetting it. I'm giving back every day for it. Can't phase me."
The pop sensation said fake stories had been written about him and added: "I'm a good person. I know that. You can't tell me different. We know the truth. As long as my family, friends, and fans are with me you can say whatever. We are all equal in God's eyes and we have a responsibility to each other."
He added: "So make up stories about fake fines and make no mention of the positive... or say when I came out of my show with my shirt off because after performing for two hours I might be sweaty I was going into a club (really?) or any girl I stand next to is my girl or that I don't care, or that I don't feel, or that a 19-year-old going to a club in Europe is wild...
"I understand it is part of the job to be judged... but judge me on the facts, judge me on the music, and be careful of the judgment you pass. But know this... I'm only judged by one power, and i serve him.
"So yeah I will continue being me. I will continue to serve, to perform, to care, to love, to smile, to dance, to play, to sing... and u are welcome to join, because I carry no hate. We got to much love for that. I'm about the music."
The 19-year-old, who earlier apologised for his late gig, added: "Gonna enjoy the day and keep smiling. So should all of u. Much love. I see u #beliebers = i love u."
