In his new song, Shady XV, which was released yesterday, Eminem talked specifically about giving Rihanna head. He spits;
Still get along with this voice cause that's the monster
So do-si-do with a sociopath, everyone who knows me knows that
What they don't know is the fact Rihanna calls me Pinocchio, meh
She loves the way I lie
Sits on my face and waits for my nose to grow
