Pink is well known for her honest approach to parenting, and not holding back when it comes to calling out online bullies and internet trolls.
This time Pink has decided to one up her usual calling out of mum-shamers, and decided to set them a challenge.
Writing on Instagram, Pink announced the challenge to her followers.
Pink described the challenge under a picture of her husband Carey Hart and daughter Willow reading together on a chair.
"I’d like to propose a worldwide internet challenge to anyone reading this today." she wrote.
"Go ONE day without criticizing someone online. Let’s call it the MISS ME WITH THE BULLS**T CHALLENGE. And if it feels good, hey, why not go TWO DAYS. But let’s start with one for the overzealous out there. #onedayatatime #onlylove"
