Kendrick really must not be lying about having someone at OVO leaking shit to him.
He knew Drake was dropping Family Matters and even mentioned it in Euphoria, and was ready with Meet the Grahams immediately after Drake dropped.
If the daughter thing ends up being false, Kendrick will lose all credibility and Drake gets an automatic win. So... I'm kinda leaning towards it being true. Especially if Kendrick has someone on the inside with information.
