Selena Gomez played a starring role on the red carpet last night at the Los Angeles premiere of The Thing.

The 19-year-old singer and actress doesn't appear in the movie - but was the main attraction at the event in a pair of impossibly short black glittery hot pants.

Gomez, who dates fellow teen star Justin Bieber, teamed her look with a floaty white top and strappy heels for her night in the spotlight.
