Do teens on television and in magazines look anything like teens in real life? Fourteen-year-old ballet dancer Julia Bluhm doesn't think so.

Bluhm has started an online petition urging Seventeen magazine to print one unaltered real photo spread a month. So far the petition has received over 41,000 signatures and Bluhm's campaign and Spark Movement blog was featured on Nightline.

"To girls today, the word 'pretty' means skinny and blemish-free," Bluhm writes. "Why is that, when so few girls actually fit into such a narrow category? It's because the media tells us that 'pretty' girls are impossibly thin with perfect skin."

Demi Lovato: Being a celebrity can be dangerous

Former Bachelor contestant Ashley Spivey, who writes a blog called Say No to Cosmo, supports Bluhm's cause. "I love stars like Jordin Sparks, Jennifer Lawrence, and Demi Lovato who have curvier figures (only relatively speaking), and also speak out against conforming to Hollywood's standards."

Both Bluhm and Spivey take particular issue with magazines.

"Seventeen Magazine is supposed to be a relatable magazine. How can we relate to computer altered photos?" Bluhm says. Adds Spivey:  "Cosmo [had a cover] where they touted Khloe Kardashian for being amazing and funny, but they had photo-shopped her to the point of being unrecognizable.  She has always been honest about having a different body type than her other sisters and if she is so amazing they should photograph her and leave the images alone. Khloe is beautiful without having a stick-thin waist and legs and Cosmo should let that resonate with readers."
