Justin Bieber showed off his six-pack abs for fans at his final Madison Square Garden show this week while bringing his 'Believe' world tour to New York City.

The 'Boyfriend' singer played several sold out shows at the iconic Big Apple venue this week, and made his fans go crazy when he removed his top during Thursday night's show (30th November).

"And I meant what I said," Justin tweeted after the show. 'I'm blessed because of all of you to do what I love. you got me smiling. I'm gonna do it again tomorrow. Even bigger."

Justin has been hitting the gym more frequently this year after admitting back in early 2012 that he wanted to get some "guns", and event recently posted several topless pictures on his official Instagram account.
