Gwyneth Paltrow... actress, cookbook aficionado and creator of high-end lifestyle brand "Goop" did something DANGEROUS! 

This is even worse than letting your kids eat "Cup of Noodle" soup!

She had her daughter, Apple, on the back of her Vespa in L.A. and cut off a school bus! The mother-daughter duo were NEARLY HIT by the oncoming vehicle.

YIKES! Thankfully they were ok, but we hope this is a lesson for Gwyneth to look before she zooms away!

Check out the whole incident below captured on TMZ. You can see her hubby, Cold Play front man Chris Martin, on a Vespa with son Moses follow shortly behind.
