The "Skyscraper" singer looked stunning in a snug n' sexy LBD as she was on-hand for Perez Hilton's "One Night" pre-VMAs party.
The outing comes as Miss Lovato recently chatted with MTV about her excitement over watching Britney Spears receive her special tribute during Sunday night's (August 28) VMA ceremony.
"Who isn't a Britney Spears fan?" Demi asked, adding, "My favorite Britney Spears song is 'I Wanna Go,' 'cause it's the latest song that she has and I love it."
Also noting why she feels Miss Spears is deserving of the honor, the 19-year-old told, "'Cause she's the ultimate pop star; nobody can touch her. She's been around for such a long time now and she's the epitome of pop. So when I think of pop music, I think of her."
