Now THIS is how you walk a red carpet!
The dancer/singer/actress twinkled brighter than all the stars in the sky in a sequin and pearl encrusted Tony Ward Couture dress and metallic Giuseppe Zanotti heels.
It was a fun, flirty look that totally worked with the theme of the event.
Brava, Julianne! You made Ryan Seacrest proud with this look!
