Canadian superstar Justin Bieber has posted an online rant via his official Instagram page, which openly bashes the negative press he has received recently and clarifies his opinions on the stories that have surfaced.

He uploaded the extensive message earlier today (March 14) and urged people to ignore the media while explaining that at just 19-years-old he has enjoyed "5 number one albums [...] seen the whole world [...] and I've accomplished more than I could've ever dreamed of":

"Everyone in my team has been telling me, "keep the press happy" but I'm tired of all the countless lies in the press right now. Saying I'm going to rehab and how my family is disappointed in me. My family is beyond proud, and nothing's been said by them, my grandparents wouldnt know how to reach to press even of they did want to so that was a lie and rehab cmon."

"If anyone believes I need rehab that's their own stupidity lol I'm 19 with 5 number one albums, 19 and I've seen the whole world. 19 and I've accomplished more than I could've ever dreamed of, I'm 19 and it must be scary to some people to think that this is just the beginning. I know my talent level and I know I got my head on straight. I know who I am and I know who I'm not."

The 'As Long As You Love Me' superstar continued: "My albums could be about anything but my messages have been to never say never and believe, not to believe in me but to believe in yourself .. I honestly don't care if you don't believe in me because I believe in me, my friends believe, my family believe, my fans believe, and look where that's gotten me so far..."

"I'm a good person with a big heart. And don't think I deserve all this negative press I've worked my ass off to get where I am and my hard work doesn't stop here... All this isn't easy. I get angry sometimes. I'm human."
