Justin Bieber goes on another rant about the press, throws Lindsay Lohan into the mix too

Justin Bieber has gone off on another rant this afternoon - following a string of pretty disastrous events for the Canadian popstar.

The 19-year-old, who turned up two-hours late to his London tour date, had a clash with a photographer and nearly fainted on stage, took to Instagram to slag off the press - and weirdly Lindsay Lohan.

Biebs posted the below essay on his Instagram page, before quickly deleting it - but not before a fan could snatch a sneaky screen-grab first.

Here's what he said:

"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 wouldn't know how to reach [the] press even [if] they did want to so that was a lie. And rehab, c'mon. 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. My message is to believe. 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, and look where that's gotten me so far . . . I'm writing this with a smile on my face and love in my heart. Letting you know first hand how I feel rather than have these [stories] linger.

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. I'm growing up finding myself while having people watch me and criticize me everyday. I think I'm doing pretty damn good.

And to those comparing me to Lindsey Lohan, look at her 2012 tax stat."

WOAH.
