So much a$$ on one stage! During the B96 Pepsi Summer Bash in Chicago this past weekend, Jennifer Lopez and Iggy Azalea performed their collaboration 'Acting Like That' off J.Lo’s new album 'A.K.A.' Iggy’s mic was not switched on during her verse and she was not happy at the "idiot" who handed her a non-active mic. Seems J.Lo is fishing for her next hit, since Iggy is now the IT kid on the block. Check out a snippet of their performance inside.
