This is cool - Josh Dun from Twenty One Pilots is now an official ambassador for goodDYEyoung, the hair color company that's run by Paramore's Hayley Williams.
In a video marking the announcement, Josh tells the story of how when they first signed to their record label, Fueled By Ramen, Hayley was one of the very first people to welcome TOP to the family. They've been longtime friends, so it's a natural collaboration.
Cheers to good people working together on good stuff!
