Is Korean sensation PSY getting a bit too Gangnam for his own good? Sources tell us the rap star rolled into Times Square for his New Year’s Eve performance with a huge posse.

One witness tells us, “PSY’s entourage was intense and set up shop in the sole outdoor tent with heating. It was for anyone and everyone performing, but once his posse of dancers came, PSY’s security locked it down, and no one else could use it for the duration of their prep time, which was probably for 20 minutes or so.” Other stars milling around included Mario Lopez with new wife Courtney and Anderson Cooper, who was heard telling Allison Hagendorf he hopes to get a new puppy this year.
