Justin Bieber sang about wife Hailey in several songs on his new album, 'Swag' - like 'Walking Away,' where he vowed not to end their marriage.

Justin Bieber sings about relationship highs and lows on his new album, 'Swag,' addressing his marriage and commitment to wife Hailey Bieber

Like much of SWAG, “Walking Away” is inspired by old-school R&B. But rather than celebrate his love with Hailey, Bieber directly addresses their issues, even questioning why “you're throwing stones at my back” and asking to reflect on their own behavior. “Girl, we better stop before we say some sh*t,” he sings. “We've been testing our patience.”
