But is the Ugly Betty star being a mean girl herself by insulting her Sisterhood co-star's show?

America Ferrera told Seventeen that TV can make girls mean.

US magazine reports the Ugly Betty star said, "Like, if you're watching The Hills or 90210, all the back-stabbing shapes the way we act -- you go to school, and you think your job is to find a sworn enemy and be jealous of each other. I mean, I love Blake [Lively] and she's a wonderful friend of mine, but shows like Gossip Girl kind of condition us to be mean."

Do you think TV shows breed mean girls?
