Christina Milian and Amber Rose got into the Halloween spirit last night, hitting up a Halloween party in L.A. dressed to kill! Though I’m not exactly sure what Chris is supposed to be, she looks fly in her catsuit and pink wig! Amber Rose opted to go as a woman from the Victorian era, while her BFF Priscilla totally killed it as Ursala from The Little Mermaid! And Christina’s fiancé Jas Prince even got in on the fun, going as a pimp daddy. LOL! Check out more pics from their night with Miley (as Lil Kim) and more in the gallery!
