Nicki Minaj must really love her fans. That's probably why, when a fan named Tatyana asked Nicki to call up her ex-boyfriend Kevin live on UStream, Nicki was happy to comply. Although Kevin didn't pick up, we still got to witness Nicki leaving a bizarre tirade on his voicemail that included the phrase, "Number sign, sit yo' ass down!" Nicki must have forgotten she was on UStream and not on Twitter. #socialmediafail
