At this point Drake has no choice but to start showing receipts for his claims about Kendrick beating on his fiance. Even if Drake has proof that she cheated or his kid is illegitimate, it literally won't matter because the only thing that could even this beef out is if he actually exposes Kendrick as a terrible human being and take him down with him.

Pusha was able to expose Drake being a dead beat because Drake's own producer was disgruntled over Drake being a deadbeat and told some girl. If Kendrick is real about his claim of OVO leaking shit to him then dude must have something damning. Like bro you cannot be talking about Drake being Beria and not having receipts
