Carey Hart is in hot water following another self-admitted parenting fail. Hart, who has two children with singer Pink, posted a video on Instagram in which the couple’s eldest daughter, Willow Sage can be seen popping balloons with his large pocket knife, reports USWeekly.com.

“Parent fail 287, letting your daughter pop balloons w/ Papa’s pocket knife (sic),” the former motocross competitor captioned the video. In the footage, the little one held a knife with both hands and stood in front of an arrangement of pink balloons. When his followers started trolling him for letting the seven-year-old use a knife, the Inked author responded with, “I’m so sorry.”

This isn’t the first time that Hart’s parenting methods have drawn negative attention from his social media followers. Last month, he faced backlash after uploading footage of Willow learning how to shoot a rifle.
