Tonight, Anna Wintour and Marc Jacobs visited Late Night to promote "Fashion's Night Out." The best parts of the interview, however, had to do with Lady Gaga's pre-performance prayer ritual (much to Wintour's chagrin) and Jacobs' morphine drip. Highlights inside.

Side note/observation: hasn't Jacobs been in rehab for an addiction to heroin before? If so, then—assuming he wasn't being facetious—why would he so willingly admit to accepting a morphine drip, surgery or no surgery? As Page Six would say... just asking!
