Bieber's brand new single is accompanied by a Rocky-inspired music video, starring Zoey Dutch, directed by Colin Tilley.

In the clip, Bieber plays a Rocky-Esque boxer who is shown training, drinking raw eggs, drinking juice, and competing in the ring. The famously tattooed singer is sans ink in the video, what caught our attention is his shaggy hair. Beliebers have noted that his look in the song reminds Bieber at the beginning of his career.

The video also features Zoey Deutch as Bieber's love interest who supports him on his journey. Throughout the video, other scenes depict Bieber weighing in before a fight, sprinting along a lakeshore, sharing intimate moments with Deutch, 26, and participating in preliminary boxing matches.

In a statement Justin said:

I can't think of a better way to close out 2020 and kick-off 2021 than celebrating with my fans all over the world and sharing this new music with them.

Music has gotten us all through so much this year, and for me personally, it's been healing and transformative. 'Anyone' is such a special, hopeful, anthemic song. It sets the tone for a brighter new year full of hope and possibility.

Fans on social media went frenzy seeing Justin's new song!
