British rapper Lady Sovereign hopped over the pond Monday night and picked up the mic in the Lower East Side at NYC's Piano's.  The 23-year-old far from average MC, aka Louise Harman, performed a full set to a sold out crowd of partying downtown-ers, including fellow British import, Agyness Deyn, who took a break from being a super model to party with her pal.
