The young Room actor is the focus of the music video, showing a personal and emotional look at how Bieber felt during his meteoric rise to fame. 

But the popstar kept busy during downtime on set and donned some strange props that didn’t make it into the music video. 

Bieber and his collaborator Benny Blanco put on extra long and large arms, that seemed to be modeled after their own. 

The singer’s even had his tattoos on them, and he had fun walking around with them fully extended.

The COVID-19 safe set, saw everyone wearing masks when not filming the music video, and the arms made it easy for Bieber and Blanco to hug from a distance.  

Though, Bieber’s wife Hailey didn’t seem to be a fan and said ‘this is terrifying.’ 

She went on to call out Blanco for likely having the idea for the larger than life arms. 

While Blanco and Bieber had fun with the crazy prop, after removing the prosthetic arms the Eastside hitmaker said they left a smell on his arms and left them ‘wet.’

Bieber and Blanco also enjoyed table-tennis at the filming location. 

Tremblay was on set in outfits that clearly signal he was taking on playing bieber in the late 2000s and early 2010s. 

The young Canadian actor wore an all white denim outfit with a purple hoodie underneath and purple sneakers as he took to a stage. 

Bieber often wore purple onstage during the early days of his career, and the color was used on his album covers.

Braun discovered Bieber by accident on Youtube back in 2008 and has been his agent ever since. 

To prepare for the role, Tremblay was even shown in the BTS working with Bieber’s choreographer to get down some simple dance moves the pop singer did during that time period. 

In the video, Bieber sits in the empty audience of a theater as Tremblay takes the stage as a younger version of him in a reflective moment on his fame.

The lyrics of the song are no less emotional, Bieber sings about being lonely despite his fame. 

While Tremblay’s young Biber is seen getting ready to perform, the adult Bieber addressed those saw him ‘sick’ and he felt like ‘no one gave a s**t* while criticizing everything I did as an idiot kid.’  

After the official music video was released last Thursday, Bieber took to Twitter revealing the song is particularly difficult for him to listen to. 

[To be honest the song is hard for me to listen to considering how tough it was to get through some of these chapters,’ he wrote.

 ‘I believe it is powerful to express vulnerability and that’s why I believe this song is so powerful,’ Bieber concluded.
