MILEY CYRUS HITS PROJECT: The scantily clad models at Marty Staff’s Survivalon booth caused only the second-biggest commotion at Project New York this week. The buxom ladies were beat out by Miley Cyrus, who made an unexpected swing through the trade show late Monday in the company of her friend Natalie Levy, cofounder of fashion line Grey Ant, and Maxwell Osborne, cofounder of Public School. The trio hit up the Zanerobe and Project official after party at the Soho Grand Hotel, where Cyrus chatted up Zanerobe founder Leith Testoni. The pop star was excited to hear the brand hails from Australia, as does her fiancé, Liam Hemsworth, who has been filming his new movie “Paranoia” with Harrison Ford in Philadelphia. She told partygoers that Hemsworth is interested in starting a men’s wear line of his own and discussed the ins and outs of the business with fellow revelers. Cyrus ended the night at La Esquina and the Electric Room, said sources.
