Demi Lovato took a risk when she wore an unconventional, nude illusion dress to yesterday's Teen Choice Awards. The nude factor, however, wasn't an illusion — it was a reality as soon as her left nipple strode down the red carpet. Yikes. But on the bright side, it's a smart accessory for any young starlet looking to transition into the adult market.

"Age appropriateness," as a concept, is pretty subjective, but Demi Lovato's nipple is inarguably R-rated for a kids' show. Yeah, you have to squint a bit to see it, but I'm willing to bet any pre-teen or adolescent boy watching last night was squinting away.

Taylor Swift, meanwhile, demonstrates how to do nude illusion without the actual nudity.

I was a little disappointed to see that Carly Rae Jepson's novelty purse made no allusions to phones, or dialing, or numbers.

How did Hayden Panettiere fit into Snooki's shoes?

Speaking of nail art, I respect Abby Lee Miller's hand game.

What's extraordinary about the cast of Dance Moms that Vivi-Anne's (white dress, front left) lack of charisma is so much stronger and more noticeable than any of presence or talent.

Gwen Stefani is still ska at her core, as evidenced by her checkered nails.
