My pal Jeannie is hosting another Madonnathon NYC on Sunday, July 20, from 8PM—2AM at Rockbar (185 Christopher St.). If you're not sure what to expect, just try to envision a room filled with shame-free Madonna fanatics sharing, caring, dancing and romancing. In the bathrooms, expect people to be drying their armpits using the hot-air blowers on the wall. You get the picture.

See you there? RSVP here.
