Emma Roberts was ''so nervous'' about not having her photos retouched.

The 'American Horror Story' star made a point of avoiding Photoshop for the #aerieReal campaign but has admitted she was ''panicking'' for the first 20 minutes of the shoot.

She said: ''Yes, of course! I was so nervous. When I first walked out on the set, I was wearing one of the cute Aerie bralettes and underwear with this cute plaid blanket, and I remember feeling excited as I was getting dressed and listening to music.

''But when I walked out, I had to do everything in my power to not run back in the room. For the first 20 minutes, I was panicking.''

However, the 24-year-old beauty's nerves were eased by her two friends joining her on set.

She added: ''They made me laugh, turned up the music, and it ended up being a silly day.''

And despite her fears, Emma loves the concept of the shoot.

She told InStyle magazine: ''I love the concept of an unretouched campaign. With all the social media that we're inundated with today, with Instagram, Facetuning, Photoshopping - all of that - makes life so filtered.

''It's so refreshing to see real people looking real and looking beautiful. Aerie is already doing it, and it's amazing. I wanted to be a part of it.''
