Sexy, or a pair of good-girls-gone-bad?

Beautiful. Her top is tiny. Her shorts barely cover her bum. Her skin is smothered in makeup. She's sexy.

This is what goes through the average 13-year-old girl's mind when she sees Vanessa Hudgens.

It was once believed - before the media invaded - that to be beautiful was to be attractive to the senses or the mind of another person.

The media have imposed such a cliched image of beauty on us that the meaning of the word has changed.

If we believe beauty lies in the physical appearance of a person, how are we supposed to save tweens from drowning in depression, or worse, dressing like hookers?

There is only one solution: we make them look up to more skanky teen celebrities. Duh.

Take 17-year-old Taylor Momsen. Not only is she a character in Gossip Girl - a show followed by many teenagers - but she is also the lead singer in the The Pretty Reckless.

In a performance last year she inspired tweens using sexploitation. The rock princess wore a corset (scarcely covering her breasts), garters and stockings. Not to forget her panda-like eyes, encircled by eyeliner.

In her single Makes Me Wanna Die, she strips to her underwear.

The mall is full of tweens dressed inappropriately - they misunderstand the meaning of beauty. Why? Because the media like to reinforce the idea that people like Taylor Momsen have a superior taste in fashion.

Does she? Or does she have good-girl-gone-bad syndrome, which Miley Cyrus probably infected her with?

Speaking of Miley, where did her brains go? Even though her popular show Hannah Montana was finishing, it didn't mean she could go around singing "I can't be tamed". She still had younger fans.

In her I Can't Be Tamed video, she wears a leotard and thigh-high boots. Well done, Miley! You found a more revealing outfit than the stripper one you wore to the Teens' Choice Awards!

Tweens have been brainwashed so much that they bring their "sexiness" to school. That's right. They trash their uniforms. This is revolting because it shows how Blake Lively - the third most-admired celebrity among teens - influences how tweens dress at school.

There are seductive images on the internet of Glee star Lea Michele posing in school uniform. Her uniform consists of a short, tight-fitting top, thigh-high socks and heels. No skirt.

Singers like Britney Spears also inspire tweens. In Britney's video of Baby One More Time, she hardly wears half her uniform.

Tweens aren't mature enough to see the stupidity of celebrities' "uniforms", so it is clear why they hitch up their skirts, half-unbutton their shirts and wear makeup, even if it costs a few detentions.

The bar has risen. Darling Willow Smith and Rebecca Black must make a choice: either to stay normal and be unsuccessful, or to starve and sex it up.

Sexy. That is how adults aspire to look and, according to the media, so do tweens.

Not so beautiful. She's vanessafied. She tayloristic. She's miley-esque. She is anything but sexy.
