Lady Gaga has taken over Barneys for the holidays. Beginning tonight at 11:59 p.m. you can head to Barneys New York and experience the Lady Gaga workshop. The entire 5th floor of Barneys has been transformed into eight mini-stores that will feature Gaga themed items such as candy, toys, apparel, accessories and holiday themed items. There will also be Gaga installations throughout the city including Columbus Circle, Broadway & 23rd, and Broadway & Houston. If you are lucky enough to be in the city, I highly suggest you check out this one-of-a-kind event. If you aren't going to be in town, check out the Gaga Workshop Site here.
