The American Horror Story star stripped down to her underwear for the latest #AerieREAL campaign, which portrays un-retouched models wearing the American Eagle brand's lingerie, and admits she was terrified she'd look washed out in the images.

She tells People magazine, "I definitely have a complex about being pale because I've been made fun of my whole life, so I was nervous about that.

"When I was a kid, everyone would be like, 'Your legs are so pale! I can't believe you're wearing a dress!' And I would get so embarrassed. I would get spray tans, and I look back at those photos now, and I just think, 'Oh my goodness, you're orange'. I would tell my younger self to stop spray-tanning so much. Just own it."

But she was such a fan of the #AerieREAL campaign she put her worries to one side and stripped off.

She adds, "I just loved the messaging behind it. I thought the whole idea was so inspiring... I hope that with this campaign they (young women) start seeing 'real' as beautiful and just who you are, inside and out."
