In reply to Paulo.

Sheezus had nothing to do with that. "RiRi isn't scared of Katy Perry's roaring
Queen B's going back to the drawing
Lorde smells blood, yeah, she's about to slay you
Kid ain't one to fuck with when she's only on her debut
We're all watching Gaga, L-O-L-O, ah-ha
Dying for the art so, really, she's a martyr
The second best will never cut it for the divas
Give me that crown, bitch
I wanna be Sheezus"

That doesn't sound like a dig to me. It came off as a song of women empowerment.
