YBN, the powerful Jay, had a pregnant mom before dating Blac Chyna

EXCLUSIVE

Blac ChynaSuspicions of YBN The Powerful Jay to cheat on her are inaccurate … at least when it comes to her ex-GF, become baby mom.

As you probably know … BC thrown his 19-year-old coin earlier this summer, because she was fed up with YBN sliding in the DMs of her chicks and she a side piece.

His announcement over the weekend that he now has a new baby – SirLucius Edward Scott-Bradley – It may seem to confirm his fears, but we were told that the baby had fallen before Chyna was in the picture.

Sources connected to YBN and the baby's mother, Dailyn Scotttell us that they met while she worked as a stylist for one of her music videos. We are told that he dropped it around December … almost 2 months before it officially started going out with British Columbia, who knew that YBN would soon become a dad.

SirLucius was born Sept. 4 in Cedars-Sinai, Australia – thus the December design trail.

The Almighty Jay was touring Europe when the kid was born, but we are told that he's been there since … to support him financially and see him as much as possible.
