Quincy Combs' Mends Relationship With Biological Dad, Al B. Sure

Quincy Combs' relationship with his estranged biological father, singer Al B. Sure, has gone from pretty much non-existent to the two of them doing a music video together.

Quincy just dropped the vid for his new song, “I Can Tell You (Nite and Day 2.0).” The track is a remix of Al's huge '80s hit "Nite & Day," and it sure feels like a handing down of the torch.

It's a big step in their relationship. If you recall ... Quincy penned an open letter years ago praising Diddy -- who raised him with his mom, Kim Porter -- for always being there when Al wasn't. At the time, Quincy said he always wondered about Al -- "Where he was? What was he doing? and most importantly, Was he even thinking about me?"
