Selena Gomez in Sherri Hill!

Things are going pretty well for teen starlet Selena Gomez right now: she's enjoying a respected career as an actress, singer, and UNICEF Goodwill Ambassador -- not to mention the fact that she may or may not be dating Justin Bieber. (Disclaimer: we have no idea! Both young superstars are obviously wise beyond their years and have not commented on the situation.)

She also recently did a live performance of the theme song for Shake it Up -- Disney's new television show -- and guess what she wore? You got it. Sherri Hill. 

Doesn't Selena look  gorgeous in her Sherri Hill dress (at left)? 

If you love how she looks, check it out for yourself: Selena's wearing Sherri Hill style # 1403 -- which also happens to be a fun and flirty prom dress option.

We're just saying. You can take a look right here.
