Teen sensation Justin Bieber has opened up about the achievements he would like to secure next.

The 'Boyfriend' hitmaker has enjoyed a phenomenal career to date, but he is showing no signs of slowing down as he explained to Rollacoaster magazine that his next aim is to pass 1 billion views on video hosting site YouTube:

"Each time I break a record I'm always happy. With my YouTube stuff, 'Baby' has more views than any video - ever. So my next goal is to reach one billion views on a video."

At the time of press, 'Baby' has 761,902,976 views. He also added that his new album 'Believe' reflects his maturity:

"I am growing up, I am now 18 and my fans are growing up with me. I'm getting older and I want that to reflect in my album - it is just more mature and reflecting the age that I am."
