Except, I know the people that actually wrote a majority of this song. She's been a "co-writer" her entire career. In No doubt Tony did all the heavy lifting writing wise, and in her solo career shes had help from many different songwriters (Linda Perry, Mark Batson(also a friend of mine), Dallas Austin, Pharrell, Kara Dioguardi, Sean Garrett). The list goes on. This song was written by Justin Tranter and Julia Michaels with life inspiration and a little help from Gwen. Fact.
