Gavin James is venturing into the world of TikTok.

A new TikTok challenge called #WeAreDifferent asks participants to showcase their uniqueness, following the lyrics of Gavin’s hit single ‘Boxes’: "we are all different underneath," the Irish singer-songwriter croons in the song.

The song itself is inspired by feeling like you don't fit into the box society has tried to fit you into. The TikTok challenge is now trending, and already has over 44.3 million videos and rising.
