Listen to P!nk Radio on iHeartRadio

P!nk stopped by Elvis Duran and the Morning Show Tuesday to talk about her upcoming album and the iHeartRadio Music Festival, but the conversation soon turned to gushing about her daughter, Willow, and opening up about fighting with her husband Carey Hart.

P!nk admitted to once slashing Carey's tires during a drunken fight and her belief that fighting is important to relationships. She also talked about how motherhood has changed her and offered some details about her new album, The Truth About Love, due out September 18.
