Beyoncé and JAY-Z's Halloween costumes are always on another level, and this year was no exception. On Sunday, the music power couple attended pal Kelly Rowland's Halloween bash dressed up as none other than the late Notorious B.I.G. and Lil' Kim. From Beyoncé's spot-on outfit to the mole above her lip, Beyoncé had Lil' Kim's look from Missy Elliot's "The Rain" music video down pat. Not to be outdone by his wife, JAY-Z also perfected Biggie's iconic look in a red leather jacket, a black cap, and a cane. Hopefully Beyoncé treats us to even more photos on her blog soon!
