Megan Fox claps back with savage response to mum-shamer: 'Wait, I have kids?'

If you have kids, it's inevitable that at some point someone will comment on your parenting.

Take them to a cafe and the second they cry someone will 'helpfully' suggest they're hungry, take them grocery shopping and you'll be told they look tired — and why are you selfishly dragging them around on your errands?

But while a passing stranger's comment is frustrating, at least us mere mortals aren't dealing with the deluge of comments thrown at celebrity parents.

Given there are actual humans behind those famous faces, sometimes they (rightfully) hit back. Cue Megan Fox absolutely serving it to a mum-shamer on her Instagram page.

The Jennifer's Body star, 36, posted a series of selfies sitting on a swing at her and fiancé Machine Gun Kelly's house, dressed in a corset and holding a book of 'Moon spells', captioning it: 'Pick me energy'.

But the snaps didn't sit well with one follower, who was seemingly unhappy that Fox should have a life outside of her children.

"Where you kids at?" the woman commented on the posts. In true Fox style, she clapped back with a snarky comment of her own.

"Wait wait wait. I…have kids?!?," she responded. "Oh my god, I knew I forgot something!! Quick, someone call the valet at the Beverly Hills hotel. That's the last place I remember seeing them. Maybe someone turned them into lost and found."

"You don't expect a dad to be with the kids all the time, but I'm supposed to not be seen and be at home with my kids," she told the magazine.
