Justin Bieber has shocked his young fans with his raunchiest video to date.

The Baby hitmaker, who has faced criticism over his bad behaviour in recent months, is further distancing himself from his teen idol image in his new promo for All That Matters.

In the video, the 19 year old is seen topless while cavorting with model Cailin Russo. The pair also shares a passionate kiss in the footage.

Bieber unveiled the video to his fans via Twitter.com on Monday (02Dec13), and has previously revealed his experiences with love and loss inspired the saucy shoot.

He writes, "The lyrics of this song are pretty self explanatory - when you fall in love with someone, that someone can make you feel whole.

"I feel like anyone who has been in love knows what I mean. The song conveys that being in love is one of the greatest feelings on Earth.

"Love is all that matters. But the void you feel when that love goes away is gut-wrenching. I worked so hard on this song in the studio - trying to put that feeling into music was extremely important to me. I'm happy to share it with you."
