Actress Ashley Benson has taken aim at Tv bosses for airbrushing away her flaws in a promotional picture for her teen drama Pretty Little Liars.

The blonde appears in the snap alongside her co-stars Lucy Hale, Troian Bellisario and Shay Mitchell, and all four women are pictured sporting red dresses and perfect complexions.

However, Benson insists she is not a fan of the heavy airbrushing used in the shot, which has reportedly been released to publicise the upcoming fourth season of the show.

She uploaded the snap to her page, adding in a caption, "Saw this floating around... hope it's not the poster. Our faces in this were from 4 years ago... and we all look ridiculous. Way too much Photoshop. We all have flaws. No one looks like this. It's not attractive."

Benson adds in a message to her fans, "Remember, you are all beautiful. Please don't ever try to look like the people you see in magazines, because it's fake. It only causes an unhealthy mind (sic) about how you see yourself. You are perfect the way you are."
