Here we have a white lady who has capitalized on black culture dressed up as a black man undercover as a white woman. Huh.
If you're familiar with 1) Iggy Azalea and 2) the internet, then I am sure you have come across that one meme comparing Iggy Azalea and Rita Ora to the flick White Chicks, wherein the Wayans brothers play FBI agents who dress up in whiteface and drag, going undercover as white women for some reason. Snoop Dogg even employed it against her in the bizarre and generally disappointing social media feud they had going recently.
So naturally, she decided that the whole thing was perfect fodder for the spookiest time of the year. Halloween 2014: a white woman in white face. Meta.
