Drew Barrymore tried out all of the products in her new make-up line while she was pregnant.
The 37-year-old actress gave birth to her daughter Olive four months ago but didn't let pregnancy stop her from working on her Flower range and even asked her husband Will Kopelman's family for help.
She said: ''My team and I tested pigments on our arms - even when I was pregnant, sweating in the summer. My family has been very involved too. Will's mother Coco has tried all of the products and given her opinion.
''I go to the lab to fight for the best formulas.''
Drew also claims her new line is perfect for busy working mothers like herself.
She told Us Weekly magazine: ''I want women to have something extraordinary. They deserve it. And with our line women are able to do everything.
''In my case, I'm a mom, I have a job and I'm running here, there and everywhere. So I need a few things in my arsenal that help me feel best about myself. Concealer and some blush help me feel young, believe me! At the same time, we offer tools for the woman who wants colour, like a notice me lip.''
