Kristen Bell's brilliant mum-hack changes everything

Not only is Kristen Bell an amazing actress and singer - but she's also a super mum with some clever tricks up her sleeve.

The Bad Moms star shared a truly brilliant mum-hack that will make your life as a parent easier and help keep your kids safe.

Kristen posted this gem to Instagram, revealing how she keeps her kids out of harm's way while she's unloading the car.

It's called "hands on the circle!" she wrote, explaining that it's "the phrase we say as we jump out of the car".

"'Hands on the circle' (the circle is the gas cap) was invented by my brilliant sister in law, and has thus far kept all kiddos safe from any oncoming traffic while I unload the truck."
