We were wondering if Vanessa Hudgens would change her look after the Big Breakup with longtime BF Zac Efron. She was celebrating her 22nd birthday in a tiny silver frock at Pure Nightclub at Caesars Palace in Las Vegas. The look was typical Vanessa—long, tousled locks, a silvery-blue eyeshadow and lashings of mascara, however we were blown away when we reached her mani—bright, metallic silver nails. Kinda something Katy Perry might pull out. Whaddya reck? Party girl or OTT?
