2015 release, the fifth album from the pop vocalist. Breathe In Breath Out is the long-awaited follow-up to her album Dignity, which was released in 2007. Breathe In Breathe Out is named after a song that she recorded with Matthew Koma, which according to Duff, "stuck with [her]" throughout the recording process of the album. She further explained: "Over the past few years of my life it's just been something that really helped me-just taking a deep breath in and letting a deep breath out. It can be a good thing, it can be a struggle, it can be a power thing-it's just a good reminder for everyone to remember to do that. It's a relief." Includes the single 'Tattoo'.
