Justin Bieber Releases Steamy Music Video for 'All That Matters'

The Collin Tilley-directed clip sees the Canadian heartthrob getting intimate with his on-screen girfriend who's played by model Cailin Russo.

The official music video for Justin Bieber's "All That Matters" has arrived in full. Directed by Collin Tilley, the sexy clip features the 19-year-old pop superstar being head over heels in love with a sexy blonde lady played by model Cailin Russo.

Bieber is also seen going shirtless and making out with his on-screen girlfriend. In another scene, the Canadian heartthrob plays his guitar while singing the sultry tune, trying to convince her that she's all that matters to him.

Released in October, "All That Matters" is the second offering off Bieber's Music Mondays series. Just a few days after the song arrived, a video of Bieber dancing to the tune in the Great Wall of China leaked and went viral.

Bieber is close to wrapping up his 10-week Music Mondays project. Earlier this week, he released "Change Me", the ninth new song in which Bieber asks his girlfriend to change him to be a better man.

In addition to preparing the release of his last new song next week, Bieber is gearing up to drop his new documentary movie, "Justin Bieber's Believe". It has been confirmed that the follow-up to the singer's smashing hit debut movie, 2011's "Justin Bieber: Never Say Never", is slated to open in U.S. theaters on Christmas.
