The 25-year-old Pretty Little Liars actress traded in her carpet outfit for a hot Oscar de la Renta dress while pulling hostess duty at the pre-show for the annual event.
“Welllll that was fun. Dying over the Britney/justin jean combo that @katyperry revived. Thank u @mtv! Enjoy the show y’all,” she tweeted afterwards.
Lucy added, “Had so much fun at the VMAs tonight. And I feel like this emoji.”
FYI: Lucy completed her look with Vita Fede and Renee Sheppard jewelry
