In the age of social media, it's easier than ever before for people to have opinions, especially when it comes to parenting.
So when Pink saw that fellow singer Jessica Simpson was being trolled for allowing her seven-year-old daughter, Maxwell Drew, to dip dye the ends of her hair purple, she did what any true legend would do, she let her eight-year-old daughter, Willow Sage, dye her hair too.
This comes after Pink told Ellen DeGeneres earlier in the year that she wasn't going to share any more pictures of her kids online because trolls can't keep their opinions to themselves.
Below are a selection of the small-minded and ridiculous comments Simpson's Instagram was flooded with after she shared pictures of her daughter's dyed hair.
"Don't like it at all !!! Much better before the color. The new color makes her look older than her age," wrote one troll.
Another added: "Why start ruining her hair so young."
Pink is blown away by young singer in her audience:Thankfully, not everyone was parent shamming Simpson.
Another commenter wrote: "DON'T LISTEN TO ALL THE TROLLS!!! Your daughter's hair looks fabulous and it is better for your hair when it is professionally done to protect the health. People have nothing better to do than criticize someone else's parenting."
In response, Pink shared a before and after picture of her dying Willow's hair an electric blue color, captioned: "I heard people were bummed on Jessica Simpson for letting her seven-year-old get her hair colored. So we thought we'd share what we did yesterday."
No stranger to parent shaming herself, Pink disabled the commenting feature on her Instagram some time ago and followed her post with the following hilarious hashtags: "#bluehairdontcare #getyourownkids #parentpoliceareactuallyjustlonelysadpeople #illdyeyourhairtoolosers #ohlookmanocomments."
So, if there's a lesson to be learned from this, trolls, it's this: if they're not your kids, they're not your problem.
