Unless you were in the studio how are you 99% sure?
Well her only studio album is known for multiple songwriting and production credits she wouldnt give to the point she got take to court lol. She did Che Pope wrong especially.
Any great rapper known for bringing a gang of other writers and producers together and "curating" have multiple skeletons in the closet considering how much other nikkas did for their projects. She tried to prove she was the mind behind her album by doing a 2nd album solo.... that no one has heard
Alleged ghostwrittens too and we know about some Wyclef ghostwrittens on Fugees too. Damn near all the great female MCs are known for ghostwriters too - Latifah, Lyte, Kim, Foxy, Nicki etc besides like Jean Grae and we already know Nas has written for female MCs before
Lauryn Hill stans still stay being goofy in 2021 aint surprising
