Drake apparently didn't take too kindly to his dad questioning the validity of his lyrics alluding to Dennis Graham's "absence" from his life. Drizzy took to Instagram to address his father's claims and said that he was saddened by the comments and that his father will say just about anything if given the platform. Drake also stated that he's never written anything untrue whether or not his father accepts it.

Drake’s pops—Dennis Graham recently made an appearance on Nick Cannon’s Power 106 show “Nick Cannon Mornings.” The two spoke about many topics, including Drake’s lyrics about him in the rapper’s songs.
When asked about the lyrics, Graham went on to say none of the lyrics are true. Graham said “I had a conversation with Drake about that. I have always been with Drake. I talk to him if not every day, then every other day. We really got into a deep conversation about that. I said, 'Drake, why are you saying all of this different stuff about me? This is not cool.' He [said], 'Dad, it sells records.' Okay, well cool."  Watch above.
