Vanessa Hudgens sweater flip flops smile disney

A smile from V. Hudge is about as rare as a clear shot of Leo's face off the red carpet, but look at this!

We caught the High School Musical cutie shopping in Los Angeles yesterday, and we're not sure if it was the sale or something Zac's been doing to her, but she couldn't seem to wipe the smile from her pretty face! Why can't she do this more often? She'd totally replace the Tis as our fav HSM starlet if she did...
