Bergdorf Goodman was a mad house during Fashion's Night Out on Friday.
SJPeePee stayed for less than 5 minutes because the massive crowd was overwhelming, but Mary J stayed to hawk her new eyewear and designer Tom Ford signed books.
Posh was also there being her usual fashionable self, although we can't say we're loving her hair style.
