‘I have been working with @environmentalworkinggroup for almost three years now to help ban toxic chemicals from our personal care products and cosmetics (think shampoo, conditioner, deodorant, toothpaste, lotion and including those for children and babies) and we finally have a major victory for the movement!’ wrote the sister of Kim and Khloe Kardashian.

‘Thank you @CAgovernor @GavinNewsom for leading on cosmetics reform by signing the Toxic-Free Cosmetics Act into law and protecting Californians! 

‘California will now ban 24 toxic chemicals from the personal care products and cosmetics we use every day. I AM HAPPY!! ‘

Two looks in one post: There were two images shared for her 102M Instagram followers. In one the Poosh founder was smiling as she pulled back her arms to show off her bare, bra-free chest. And in another the mother-of-three crossed her arms and wore a more serious expression

There were two images shared for her 102M Instagram followers.

In one the Poosh founder – who has been hanging out with Tik Tok star Addison Rae lately – was smiling as she pulled back her arms to show off her bare, bra-free chest.

And in another the mother-of-three crossed her arms and wore a more serious expression.

The siren’s raven hair was worn straight and down around her face as she had on light makeup that included filled-in eyebrows and fake eyelashes.

This comes after the siren showed off her stunning Halloween decorations.

On Wednesday evening the reality TV maven gave her Instagram followers a look at her spooky decor which seemed to have a black-and-white theme.

In the images there was a skull, spider webs and mini pumpkins in the Calabasas, California mansion she shares with her three kids, Mason, Penelope and Reign whom she co-parents with ex Scott Disick.

A realistic-looking skull was seen on a table next to a lit purple candle with a thin dark purple vase and a large round crystal decanter with a long neck and round stopper.

There was also a bunch of white roses and white cobwebs with the hand of a skeleton.

And on a beige runner were small beige pumpkins.

Also seen were bone colored long tapered candles in silver, old-fashion looking candlesticks that were lit adding a haunting look.

In the background was a standing silver skeleton with a black hat on his head.

And on the walls were paintings with Eighties looking black-and-white geometric patterns.
