Yes Ciara sis let them know but Nicki didn't even mention Kim out of the blue, THEY (Rosenberg) asked Nicki who were her favorite female MCs growing up and she answered: Foxy, Kim, Lauren, & Remy (not in that order but you get my point)
She just wants Nicki to STOP talking about her in every interview that's all.
But nicki hasn't mentioned her in every interview. You can count on about a hand how many interviews she's mentioned Kim on...on the other hand over the past 3 years you can count on one hand how many interviews Kim hasn't mentioned nicki in
