Miley Cyrus strutted (with security) into hot spot Acme to her own song “Party in the USA” Wednesday, in celebration of her new Cosmopolitan cover. The mag’s editor, Joanna Coles, told us of her current obsession with Cyrus: “If I had ‘Single White Female’ tendencies, I would be ‘Single White Female’-ing Miley.” Also at the bash were Cyrus’ mom, Tish, and Oscar nominee Quvenzhané Wallis. A night later, Cyrus was seen at Marc Jacobs’ Fashion Week show.
