Apparently Gwen Stefani talking to a radio station about her divorce is a weekly thing now, and this week she's getting much more candid. And get this: Stefani found inspiration to split up with husband Gavin Rossdale by … listening to her old No Doubt breakup songs. "I go back and listen to a lot of that stuff and get sick," she tells Washington, D.C.'s 94.7 Fresh FM. "You look at the song and go, 'That was a red flag and that was a moment where I was feeling just as bad as I do today and why did I keep it up?'"

As for the divorce itself? She's looking on the bright side. "I wish it didn't happen. I wish that all this wasn't happening, but it was part of my life journey," she says. "In my life I've had two really bad heartbreaks, but I've written some really incredible music out of it." See? She really is a big fan or her work.
