Justin Bieber goes on the defensive: ‘I’m not fat- it’s just the angle’

Justin Bieber has gone on the defensive after posting a topless birthday pic.

The pop star is pictured staring out into the distance in his latest Instagram pic.

Though he by no means looks ‘fat’, Justin felt he had to address Internet trolls before they even tried to criticise his physique.

Justin shared snap with the caption: ‘Great birthday… and I’m not fat its’ the angle’.

Of course, this didn’t stop the Internet trolls writing ‘fatty’ underneath Justin’s special birthday message. Clever, guys…

But the Biebs is clearly having the last laugh as it looks like he’s spending his birthday in a very lovely, hot-weathered location.

Anyways before we forget- Happy Birthday JB! Now you're 21 you can have your 'first' beer...
