We almost didn't believe our tired, weary eyes when we saw this BlackBook cover with Nicole Richie. At first we thought it was Lady GaGa. Then we thought Peaches Geldof. Makes sense, considering both have been everywhere lately. But instead, it was pixie mommy Nicole Richie. What, they couldn't get the no-pants-wearing-singer to grace the cover of their music issue instead? And is that a wig Nicole's wearing? Either way, we'll admit she looks pretty hot in all those Sprouse get-ups. See more of the pint-sized social wearing a plastic dress from Target and channeling her best inner Gaga after the jump.
