It's impossible to find a woman between the ages of 25 and 45 that doesn’t know every word to the song "Unwritten" (or at least to the chorus that starts with the catchy “feel the rain on your skin"). This week, the song's writer and artist, Natasha Bedingfield, sits down with Perrie to talk about what she wore while writing the Grammy-nominated tune, as well as what it means to be an authentic mother, why she hates wearing jeans, and her latest album, Roll With Me.   Follow @natashabedingfield on Instagram and @natashabdnfield on Twitter. Find her newest album, Roll With Me, wherever you get music.
