On your new album, you’ve written about your former husband, Bush frontman Gavin Rossdale, and new boyfriend Blake Shelton. Did you get nervous sharing such personal songs?

I don’t have any secrets; I don’t have anything to hide. I haven’t done anything wrong. I’m happy to share my story. [This] is really the only record I’ve written that’s mostly happy; all the others are about heartbreak. And there’s some of that on here—it needed that, to make the rest feel as good as it feels.
