Blake Lively stars in L'Oréal's new beauty campaign.

The 29-year-old actress - who was announced as the spokesperson for the beauty and skincare brand in 2013 - features in L'Oréal's new True Match foundation commercial for their 'Your Skin, Your Story' campaign, and the blonde beauty has admitted the advert has strongly ''moved'' her because it celebrates every woman's ''similarities and our differences''.

The former 'Gossip Girl' star shared a picture of her portrait in black and white on her Instagram account with a quote from her emblazoned across it, which read ''We are different shapes and sizes. We are different colours. We are beautiful inside and out. We are kind. We are brave. We are vulnerable. We are flawed. We are perfect. We are worth it ...''.

And the blonde beauty - who has daughters James, two, and two-month-old Ines with her husband Ryan Reynolds - captioned the post: '''Because I'm worth it' is an iconic belief that resonates with so many, for good reason. Now more than ever that simple phrase is a powerful reminder to us all, as woman are coming together, rising up, and standing for their value. We are worth it. We are different shapes and sizes. We are different colors. We are beautiful inside and out. We are kind. We are brave. We are vulnerable. We are flawed. We are perfect. We are worth it. And we each have a story to tell. Which is why I was so moved by the 'Your Skin, Your Story' campaign. It's a beautiful illustration that we are in this together. And we are listening to one another and celebrating each other for both our similarities, and our differences. Now THAT'S beautiful.'' -Me :) #worthsharing #truematch (sic).''

Blake took to social media to share a link of her talking about the product and in the footage the star admitted she likes to give the illusion she is not wearing any make-up when she is, although she has revealed she doesn't like to don a face full of cosmetic products.

Speaking in the clip, she said: ''I am from Southern California. I am English, Irish and Cherokee, so my family is from all over. To look back over my heritage and see where my family has come from is neat.

''I like when I'm wearing to make-up to look like I'm not wearing make-up, I like not wearing much, so this is just something that complements and enhances your natural beauty without adding a mask on top of it. My true match is W3 and I'm worth it.''
