Beyoncé and JAY-Z's Halloween costumes [1] are always on another level, and this year was no exception. On Sunday, the music power couple [2] attended pal Kelly Rowland [3]'s Halloween [4] bash dressed up as none other than the late Notorious B.I.G. [5] 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!
