Selena Gomez Shows Off Her Mile-Long Legs

Steven Gomillion and Dennis Leupold for Elle Mexico

If her acting and singing careers ever nosedive, Selena Gomez certainly has a back-up option: modeling.

The Disney darling, who turned 19 just five days ago, looks a solid decade older in her new photo shoot for Elle Mexico's August issue.

Paired with pale, earthy clothes and '70s-style cuts, the sepia-toned pics play up the shoot's retro feel.

Even though we're getting used to seeing Selena in magazines, these new shots give us a whole new respect for the rising star - the pics are gorgeous and seriously, when did her waist get that tiny?!

Talk about knowing how to vamp it up ... and still stay clothed (yes, we're talking to you former-and-current-Disney-stars-who-shall-remain-nameless).
