The 'Boyfriend' star teases fans with a picture of his toned torso in the behind the scenes picture.
Justin Bieber has been showing off his six-pack abs to fans on Twitter while continuing rehearsals for his current 'Believe' world tour.
The 'Beauty And A Beat' singer shared a topless picture of himself last night (5th November) in the middle of rehearsing his moves alongside choreographer Nick i Demoura.
Justin is seen taking the picture in a mirror wearing Calvin Klein boxer shorts, blue jogging bottoms and trainers while also showing off his toned torso.
The picture follows several behind the scenes shots Justin uploaded last week of him showing off his arm muscles, after admitting earlier in the year that he is keen to "get some guns on the go" by working out in the gym.
