Miley Cyrus got glamorous in a white maxi skirt to celebrate her Cosmopolitan cover in NYC last night. She smiled and posed for pictures with fans on her way into the party. She also reunited with the magazine's editor in chief, Joanna Coles, for last night's festivities after joining her under the tents at Lincoln Center for a bit of fashion fun earlier in the day. Miley sported a bright red jumpsuit to take in Rachel Zoe's collection yesterday. She was also accompanied by her mom, Tish Cyrus, who took a front-row seat next to her for the show. It has been a big week for Miley, who has been making her rounds on the party circuit. Over the weekend, Miley wore a sexy Emilio Pucci number for Clive Davis's star-studded pre-Grammys gala in LA.
