I think they're lyrics but that's not really an excuse. She also thought it was okay to sing songs and not skip the n word.
Also she's deleted her tweets but she seems to have also got into a back and forth with people about a Beyonce video. It's 2016 and I know Formation rubbed some people up the wrong way/lost Beyonce fans because it was too heavy on the black power, so I'm guessing it's that.
People are telling Lek that the video/song is meant to be uplifting for black people/women and saying that's why she doesn't understand. From the replies it seems like she was questioning the imagery in the video or maybe the lyrics. N*gro nose etc.
Bit rich seeing as she loves to wear braids!
She can't question one aspect of black culture while stealing another.
