Nineties singer Al B. Sure's son with former model Kim Porter is airing his dirty laundry on the 'net via a letter, which is accompanied by an emotional song. Quincy Brown, who was raised alongside Sean "Diddy" Combs children, grew up in the limelight due to his mother's longtime relationship with the entertainment mogul, but now the 17-year-old is speaking out about his biological father's absence.

"I grew up without my father, an irreplaceable force and influence that was absent in my life. I watched other kids enjoy the embrace of theirs, and I searched for a way to reconcile the meaning of my circumstance," Brown writes in the letter.

The teen goes on to confess his pain and frustration, but reveals that Combs has been a great father figure. "Sean Combs is the person whom I look up to and appreciate as a father. He is the one who help mold me into the person I am today and will always try to live up to his expectations. He has always been supportive of me and I will forever love and respect him."

Diddy showed his love for Brown aka iQ and pulled out all the stops for the teen when he turned 16 almost two years ago. MTV chronicled Brown's lavish "Stunna 16" for the network's 'My Super Sweet Sixteen' series. Al B. Sure reportedly failed to appear at his son's birthday party.
