The 2013 Teen Choice Awards were a more casual affair, with your favorite pop stars turning up in street style attire as the walked the carpet.

By no means did "casual" translate to "sloppy," since so many of our faves looked amazeballs. Selena Gomez, Demi Lovato and One Direction were some of the evening's headturners on the red carpet tonight (Aug. 11).

Sel Go was sexy in a body-hugging emerald green dress with cutouts and slits, which she paired with nude heels. She also rocked mega-long extensions. SEXY!

Demi Lovato donned her usual rocker chic. We love the black leather leggings and embroidered blazer, along with that punky pompadour. And those boots mean business. Lovato's style is so enviable and consistent.

Jordin Sparks donned a body con, blue and white striped swirl of a frock with a halter neck. She was just as sexy as Selena. No wonder her longtime BF Jason Derulo is soooooo taken with her.

One Direction -- handsome as ever in urban chic, with jackets and jeans. Liam and Louis and Zayn and Niall and Harry were all unique when it came to their outfits, but their overall look was complimentary. Kudos to their stylist for creating this "concept" and pulling their looks together.

Although, we must admit that Harry looked to be going on safari. Is that Harry on holiday? Whatev the case, he's SUCH a hunk and a hottie. Look at those tattoos peeking out of his shirt. Rawr.
