DRAKE FINALLY FESSES UP TO BEING A DAD ... ON NEW ALBUM

Drake has finally come clean -- admitting he's fathered a son -- even rapping about the paternity test he took to know it was for certain.

Drizzy released his album, "Scorpion," Friday and, as expected, it's full of glimpses into the rapper's personal life. His song "Emotionless" is the first to acknowledge his secret son  PUSHA T exposed in a diss track last month.

"I wasn't hiding my kid from the world. I was hiding the world from my kid."

The rapper reveals he's taken a paternity test for the kid too, leaving no doubts in the song "March 14."

"Yesterday mornin' was crazy. I had to come to terms with the fact that it's not a maybe. That sh*t is in stone. Sealed and signed. She's not my lover like Billie Jean. But the kid is mine. Sadie used to tell me all it takes is one time. And all it took was one time. Sh*t, we only met two times."

The album also features a previously unreleased track with Michael Jackson. 

TMZ broke the story ... Drake's been financially supporting baby mama Sophie Brussaux since the birth of their son last year. Sources close to the rapper told us last month Drake was planning to take a paternity test to figure out any future legalities.
