The pop superstar struck a number of poses in the studio while wearing items from Adidas' NEO sports and casual wear winter collection.
Incorporating a keyboard, a drum kit and a microphone into his shots, Justin ensured that his passion for music came across throughout the new lookbook, as well as his interest in fashion.
In some of the photos, the 19-year-old can be seen wearing a red checked shirt with jeans and black and red Adidas trainers.
The sleeve of the shirt is also rolled up to reveal his almost complete tattoo sleeve.
Other pictures from the NEO lookbook, Justin is wearing a striped T-shirt, black and purple trainers and a pair of grey, fitted jogging bottoms.
As well as the various music studio pictures, the singer has filmed five short movie scenes for the Adidas teen lifestyle brand.
Speaking about his involvement with NEO and the latest winter collection, Justin said: "Living your style is about being who you are and showing your own creativity, and for me that's what NEO is about.
"It's about every teenager working a different look and showing off their own unique style! I love fashion that's authentic and all about the individual, just like my music."
Vice President of the NEO Label, Claire Midwood added: "Justin is the perfect style icon to communicate the energetic feel of the range."
Justin is currently on his 'Believe' world tour and has been travelling across the globe to perform for his fans.
Earlier this month, the 'Never Say Never' star visited Beijing and even found time to walk up the Great Wall Of China - although he was carried some of the way by his bodyguards!
