In a new promotional video for the emoji, called "Ben's Story," Alessia Cara's latest hit "Scars To Your Beautiful" serves as a soundtrack for the latter portion of the story.

The anti-bullying campaign, which is being referred to as the #IAmAWitness challenge, asks users of these apps to create a 15 second music video to "Scars To Your Beautiful." In the video, they must illustrate what should be done when someone witnesses bullying in action. Other musical.ly influencers such as Kristen Hancher, JoJo Siwa and Johnny Orlando and more will also contribute to the challenge.
