NEW YORK: Miley Cyrus partied into the early hours of Sunday morning after hosting 'Saturday Night Live'.  The 20-year-old pop star celebrated a job well done with the cast and crew of the comedy sketch show on Saturday evening, dancig long into the night at New York City hotspot STK Midtown.  A source told the New York Post newspaper: ''They sat Miley in a booth by the window, and there was so much paparazzi at the window, they had to move her. But she went around the room and was very gracious to all the other cast members and musicians who were there, thanking them and saying, 'Great job.'?''–EX
