Pink is defending her husband, professional off-road racer Carey Hart, after a fan accused him of having a "complete lack of regard for proper care or concern at times" with the couple's two children.
The drama began after the singer posted a photo of her son, Jameson, with chocolate smeared on his face.
An Instagram user named sporty_mom5 commented on the photo and slammed Hart saying: "I love your music, your kids are beautiful, but your husband, I'm sorry, lacks the responsibility your kids need in his care," she wrote.
The remark didn't go unnoticed by Pink, who wrote a lengthy response to the fan.
"You sound well informed on the performance of my husband as a father," she began.
Pink went on to clap back at the Instagram user, saying: "These are bold statements from a social media spectator."
