According to the New York Post, YBN Almight Jay said in March, 'I don’t wear condoms...I would not want to f**k a b***h I did not want to get pregnant,' adding 'If Chyna got pregnant, I would keep that s**t like, ‘Ohh daddy love you, I love that a**'.’
Chyna, 29, has a child from a previous relationship with rapper Tyga - King Cairo, 4, and with reality star Rob Kardashian - Dream, 1.
According to US reports, Rob Kardashian is 'furious' over the pregnancy, with Tyga also concerned for his young son.
Chyna has been involved in a legal battle with Kardashian and his family since July 2017.
Blac Chyna's rep responded to reports of the pregnancy, saying: 'No clue. I only handle appearances and don’t ever comment about my clients personal lives.'
