According to The Sun, the glamour model is over six months pregnant, with Fazer said to be thrilled at becoming a father.
A source told the newspaper: "Ashley is over six months pregnant and Fazer is really happy. He has told his family and close friends.”
Fazer - real name Richard Rawson - is not the first member of the Camden trio to become a parent, with Dappy already a dad to sons Gino and Milo.
Fazer is expected to reunite with Dappy and Tulisa next year to record another N-Dubz album, with The Killer hitmaker previously telling The Metro: "N-Dubz will always be the base, no matter what happens we'll always come back and do N-Dubz."
