Pink says being a mother has helped her lose some of her "edge".
The singer and her husband Carey Hart welcomed their baby daughter Willow into the world in June last year.
The 33-year-old has always been known for her rebellious attitude, but says motherhood has brought out a different side to her.
"I've softened, and I think it's perfect," she revealed to MTV.
"It's what I needed. I was hoping for a little edge loss."
Pink and Carey met in 2001 and have since had a famously tumultuous relationship, resulting in a temporary split in 2008.
The professional motorcross racer knows his wife well and has observed how she has changed since becoming a mother.
"She's changed like a light switch," he said.
"I think overall she's been softened, while the mama-bear nails have been sharpened."
Whereas the couple have settled into parenthood well, Pink says the initial process of discovering she was pregnant didn't go to plan.
"I had this vision in my head that it would be this moment and I would pee on the stick and the line would appear and I'd come up with this super romantic way of telling Carey about it," she recalled. "It was so typical me. The line was so faint that I wasn't sure, I threw it at Carey and said, 'What does it say?' He looked at it and he said, 'You're knocked up.'"
"I was just happy to hear the words," Carey added.
"I didn't care how she told me. Finally it was like, 'Oh, yeah, it happened. We're going to have a baby.'"
