Nicki Minaj, who has been particularly online as of late, has filed a lawsuit against a vlogger who called her a cokehead. As TMZ reports, the rapper has filed a defamation suit against Marley Green, who goes by Nosey Heaux on the internet, for a video that she posted on Monday in which she claimed Minaj was “shoving all this cocaine, shoving in all this cocaine up her nose.”
