The new arrival would be the 29-year-old rapper`s fifth child as he already has four kids, including his first Reginae, who was born when he was just 15 to Antonia `Toya` Carter, whom he was married to between 2004 and 2006.
Wayne - whose real name is Dwayne Carter Jr. - has three other children, who were all born after 2008; Dwayne III, whose mother is unknown, Lennox Samuel Ari, born to actress Lauren London, and Neal, with singer Nivea.
Wayne looks set for a busy 2012 as he is releasing a memoir in November based around the transcribed entries from journals he wrote while in jail for eight months at New York`s Rikers Island prison on gun possession charges in 2010.
Ben Greenberg, executive editor at Grand Central Publishing, previously said: "He kept detailed journals of his inner and outer life while he was on Rikers Island, and they certainly tell a story."
